Beam SatMagazine May 20105European Workhorse: CET GmbHCET Teleport is one of Europe`s major teleports and was built by Deutsche Telekom in 1987 for satellite broadcast and VSAT services. The Teleport is located in northwest Germany giving it a commanding view of the skies, with visibility from the Eastern Pacific, the West Coast of the USA, South America, and covering Europe and Africa all the way across Russia and China, and all of Asia and down to Australia. The Teleport is host to more than 50 antennas from 15m downwards, operating in C-, Ku-, Ka-, Kand X-bands, fully integrated into Deutsche Telekoms German fiber network, providing CET with access to the terrestrial network for Internet connectivity as well as data and voice backhaul. Access to BTs Global Media Network (GMN) via BT Tower allows for the transmission of video enabled MPLS data & voice services. The STM fiber between the CET hub and the Tower is bi-directional and fully redundant. The teleport has a potential of accessing more than 200 geostationary satellites, located from 58 degrees West to 76.5 degrees East, providing coverage and connectivity across most of the visible globe.All photos courtesy of CET GmbH

CET Teleport GmbH (CET) is a teleporting services provider whose Hameln teleport has enjoyed an excellent reputation for the quality of the network operations that it has offered to its users over the years. The teleport is run by a management and operations team of highly experienced and respected satellite industry professionals who can devise and implement solutions to most of the satellite based communication problems encountered by organizations. The Teleport provides a wide range of media broadcasting and corporate VSAT services. However, in contrast to most teleports, CET sees its major VSAT market not as the ultimate end-user, but as a solution for organizations, including other teleports, who are unable to provide the service their customers require. Such challenges include... Satellite that is to be accessed that is not visible from designated remote locations or hub There is a lack of space for additional antenna(s) at the hub Shorter and/or more reliable backhaul SatMagazine May 20106 Beam

Accessible space segment unable to be obtained elsewhere CET already has a fully redundant dish pointed at the required satellite CET also provides, monitors, and manages remoteto-remote, roof-top to roof-top SCPC links, and can connect ISPs to the Internet as well as offer GSM backhaul and connection to the PSTN or to VoIP switches for voice and voice and data services. Once contracted to provide a service, CET is able to manage as much, or as little, of the project as the customer may require. This can range from site survey through installation and commissioning to the provision of licencing and on-going maintenance. The Teleport has extensive disaster recovery facilities plus a 24/7 Help Desk that is backed by a large and highly experienced engineering team who manage and maintain the satellite and hub equipment on site and at numerous remote locations. CET has both iDirect and HNS Directway hubs installed at its Hameln facility in order to offer a full range of shared hub facilities to its customers, as well as providing SCPC star or full mesh networks when required.ServicesBroadcast Services CET Teleport is expanding its range of broadcast services to provide tailored solutions to broadcasting organizations across the industry, offering Direct-toHome (DTH) Multiplexed Services as well as facilities for Playout and Distribution, Turnaround, and Occasional Use/SNG services. CET can also provide access to some of Europes premier DTH bouquets and multi-point content access and storage facilities. By using the latest hardware technology and software solutions in its studio and editing suite, CET can provide global content distribution.VSAT and Carrier Services CET provides the following services and more... Hubbed and SCPC VSAT Corporate and Enterprise Services GSM Backhaul Services Voice Services Carrier and VoIP Disaster Recovery Networks The Company can arrange local licensing, installation and maintenance with Service Level Agreements guaranteeing the highest level of availability. Government, Military, and NGO Services For many years, the Hameln teleport has provided voice and data satellite services for government agencies, non-governmental organizations (NGOs), and various branches of the military. These organizations prefer to use satellite links, even when terrestrial ones are available, as they can have virtual private networks (VPNs) and highly cost-effective actual private networks. In this way, they can enjoy much more secure communications over their own exclusive links than is possible using public voice and data networks. Other Services CET Teleport also provides all the services required to ensure customers obtain a system that is tailored to network monitoring and management, third party hosting and data storage and, for satellite operators, telemetry, tracking and control (TT&C) services.

SatMagazine May 20108 Co-Location + HostingCET is able to provide co-location and hosting facilities to service providers whether they want to locate a major antenna system at the hub or rent rack space for their down or sent up using a CET antenna. Back-Up Power SystemCET`s warm stand-by 1 MW generator is more than capable of providing all the power the teleport requires to continue operating in the highly unlikely event both of its independent mains power supplies fail. To cover the time between a power failure and the generator coming on stream, the battery pack installed is capable of supporting all the systems at Hameln for at least 30 minutes. Fiber ConnectivityHaving been built by Deutsche Telekom, the CET teleport multiple links to ensure complete continuity of service at all directly to the BT Tower in London and Telehouse no or backhauled, CET has the connectivity in place to handle such needs. Through its Internet portal, CET can provide high speed and high capacity access to various Internet Beamportals using diverse routing to ensure that Internet connectivity is always available.Ken Armstrong, CEOIn 2008 Ken spearheaded negotiations with Stratos to conclude the acquisition of the teleport facility. Ken started his career at British Telecom in 1965 and was involved in the development of its backbone System X switching system. He later moved to Audio Conferencing and then Broadcast Services.Matthew Ivey, V.P. SalesMatthew joined CET Teleport in March of 2010 to manage all of CETs sales activities. Neil Ashworth, Dir. Business Development/StrategyAfter a career with ICL and Rank Xerox, Neil became a founding director of BankNet in in Central and Eastern Europe in 1992. His last position prior to the CET appointment was as Regional Director responsible for CEE, Russia & CIS and the Middle East at Paradigm Communications.

SatMagazine May 201011 The Teleport Industry Is Looking GreenEnergy costs are spiraling upwards while carbon footprints and sustainability have become the rallying cry. In addition, customers are increasingly including power consumption and green initiatives as decision criteria in contracts and equipment purchases. So its not surprising to find the satellite industry, and in particular the teleport sector, taking on the Go Green challenge. Beamby Robert Bell, Executive Director, World Teleport Association

A growing number of teleport of excessive energy consumption now has a silver lining plenty of room for savings. Cutting teleport energy usage through green initiatives is a relatively easy way to reduce the energy bill by anywhere from 20 to 40 percent.The Road To GreenA recent IDG Research Group survey of more than 350 IT professionals found that the primary reasons for companies adopting green solutions include; reducing company energy costs (74 percent), extending the life of hardware (50 percent), reducing IT maintenance activities (39 percent), improving corporate image (37 percent), reducing emissions and energy consumption (31 percent), and freeing up space on the datacenter Kenneth A.

Consider that a copier left on 24/7 costs between US$150 and $200 a year. Soft drink vending machines are energy hogs at $350 a year. Leaving a computer sitting idle costs about 3 cents an hour. Add up all the computers in a teleport and that can quickly turn into Furnaces, boilers and air conditioners are also energy guzzlers. New heating and cooling systems feature energy-saving technologies and use eco-friendly refrigerants. Considering that heating and cooling equipment can represent at least half of the energy cost at a teleport, regular maintenance and replacement Then theres the obvious, although generally overlooked, items such as ensuring that the weather stripping around doors and windows is tight, or harvesting natural light when possible instead of Green In ActionHauppauge, NY-based teleport Globecomm Systems, for example, received high marks for having proper lighting in various task areas. Says Frost, Globecomms Hauppauge teleport has all and manufacturing spaces. Its a benchmark facility that has updated its HVAC, control room and teleport infrastructure. Globecomm, in fact, has segregated the HVAC for employees from the one for critical components. The HVAC dedicated to keeping employees comfortable has its own monitoring and control to keep the temperature steady. The critical component area includes ambient cooling so when the temperature outside drops below 45 F, the HVAC routes outside air into the system for cooling.SES, the global telecommunications satellite operator greenhouse gas emissions in 2010. The plans currently under implementation at SES headquarters in Betzdorf, Luxembourg, are expected to yield a reduction of approximately 17 percent of the groups carbon dioxide emissions as measured in 2008. Under the carbon reduction plan now under fuel oil as the main energy source by natural gas, and the cold water chillers currently in use on the Betzdorf installations. These initiatives are expected to reduce consumption by more than 500,000 m3 a year, and will also considerably cut Betzdorfs water consumption. To ensure uninterrupted operations, the new chiller systems are being installed in three stages which are expected to be completed in May 2010. Since early January 2010, the Betzdorf campus uses electricity sourced from renewable energy hydropower in this case, which can be considered CO2-free when compared to the electricity produced from the standard primary energy mix of fossil fuels and nuclear power. In addition to reducing carbon less ozone-destroying refrigerants, which further minimizes their environmental impact.Green Teleport Of 2010On March 16, during its annual Teleport Awards for Excellence, WTA announced the recipient of Green Teleport of the Year Award.

In the spring of 2006, Essel Shyam established a green initiative that includes use of solar heating and establishment of a comprehensive plan for use of consumption by up to 15 percent in three years; maintaining the air-conditioning within the facilities at a temperature 0.5 degrees higher, resulting in 18-20 percent savings over three years; and remodeling the emissions as well as using recycled materials in future infrastructure where possible. Essel Shyam took on the green initiative with innovative techniques designed to maximize the surrounding environment as well as the seasons. While the companys efforts may not be the latest in high-tech, theyve realized a reduction of energy consumption of 8.5 percent in the last year. The company is yet another example of what can be accomplished when management sets green as a corporate goal.

SatMagazine May 201016 BeamGrowth On The Horizon For The MSS SectorAs the economic climate of 2009 was still under the sway of the global economic crisis that started in 2007, the MSS (Mobile Satellite Service) industry was largely stagnant in 2009 some MSS operators even reported a decline in revenue. Global wholesale revenue stood at $1.27 billion for the six MSS operators currently active, reflecting 2.8 percent industry growth from 2008 the lowest for the last three years (though still higher than the growth in 2005, when the MSS industry suffered from a post-military conflict effect). by Wei Li, Analyst Euroconsult

PAGE 17

SatMagazine May 201017 from one to another. Inmarsat and SkyTerra are the only operators to have maintained revenue growth during the year, while Iridium, Globalstar and Orbcomm all reported a decrease in revenues. Even though Euroconsult estimates that their annual revenues did not grow given the unfavorable market situation. In terms of market share Inmarsat and Iridium maintained their leading positions, together accounting for 80 percent of MSS wholesale revenues in 2009 with Inmarsat alone having approximately 55 percent. Due to system degradation, Globalstar lost ground to competitors and ended the year with only 5 percent market share after reaching 7 percent in 2008. Nevertheless, the company announced that Beamit has slowed the loss of customers for two-way communications, and was successful in acquiring customers for the low cost one-way SPOT service. In addition, its management believes that the worst of customer defection is over. Market share distribution among other operators remained roughly the same as in 2008, with Thuraya, SkyTerra and Orbcomm having approximately 10 percent, 3 percent and 2 percent market share, respectively. Attracting New Customers In A Difficult Economic EnvironmentWith the turmoil of the global economy, customers in MSS vertical markets have tightened spending on new services. Many previously planned MSS installations were postponed or even cancelled during the year.

PAGE 18

SatMagazine May 201018 BeamDespite the recent release of more capable and lower cost MSS products (for instance, Iridium 9555 and Globalstar SPOT 2.0 ), new customer acquisition has Iridium Globalstar, and Orbcomm in revenue from their equipment businesses, a key indicator of new customer acquisition. In the case of Iridium, equipment sales fell by 30 percent in 2009, while Orbcomm revenues on equipment sales fell dramatically, representing a mere 7 percent of 2008 equipment sales revenues. Business from existing customers resisted the economic downturn well. Inmarsat and SkyTerra who primarily build business around airtime service with limited equipment sales, maintained revenue growth during the year. Inmarsat reported $695 million in revenue for its core business in 2009, a 9.5 percent increase from 2008, while SkyTerra reported 2.3 percent revenue growth, although its total revenue (around $35 million) is still only a small fraction of global MSS wholesale industry revenues. Iridium also reported 11 percent service revenue growth in 2009 despite the decrease in equipment sales. Exceptions to this positive trend are Globalstar and Orbcomm, who suffered from satellite degradation or in-orbit failure; thus it is assumed that the decrease in their service revenue is not directly due to the economic downturn. Export Credit: Helping MSS Operators Secure Financing For Future Satellite FleetsExcept for Inmarsat and Thuraya, MSS operators are currently in a major satellite replacement phase with high capital expenditures. All three LEO satellite constellation operators Globalstar, Orbcomm constellations over the coming years. In spite of the to export credit agencies. Iridium has the highest capital expenditure requirements ($2.7 billion as reported by the company) among MSS operators for its Iridium NEXT constellation scheduled to launch in 2014. The company is currently in talks with the US Export-Import Bank and the French export credit agency Coface constellation. Globalstar is already in the replacement generation satellites planned for late 2010 or early 2011; the total cost for the 24 satellites together with the ground segment was reported to reach about $1.29 billion. In June 2009, Globalstar secured $586 million a deal backed by Frances Coface. This export credit has enabled Globalstar to pay its supplier to proceed with satellite construction, and the company expects to restart subscriber growth with the initial launches of its next generation satellites.Aeronautic + Maritime Markets: Future Revenue Growth AreasThe pending launch of next-generation satellites should introduce a wide range of new products which could drive the MSS industry to a higher growth period. According to Euroconsult s Mobile Satellite Communications Markets Survey, Prospects to 2018, global wholesale revenues in 2018 will reach nearly $2.46 billion, representing an almost 8 percent CAGR between 2009 and 2018. The current largest market segment, land mobile, is expected to remain in the leading position in 2018, with about $1.41 billion in wholesale revenues. However, as most vertical markets in the land mobile sector are already considered mature, key growth areas for both established MSS players and new entrants will be the maritime and aeronautic sectors.

PAGE 19

Beam Aeronautics is expected to be the fastest growing MSS market over the next decade with a CAGR of 12 percent in wholesale revenue through 2018. Key addressable markets of the sector are cabin and cockpit communications for business aviation, commercial airlines, and general aviation, as well as cockpit and sensor data transmissions for military aircraft notably for UAVs (Unmanned Aerial Vehicles). Despite several unsuccessful ventures with commercial airlines (such as the recently reported contract termination between OnAir and RyanAir), the generally positive MSS usage experience with business jets, airlines (e.g., Emirates Airline) and other aeronautic sectors, along with a more favorable economic climate, should help MSS services achieve a greater level of acceptance in the aeronautic industry.MSS solutions from Iridium and Inmarsat have become factory options for a number of established aircraft manufacturers, and as of year-end 2009 there were more than 37,000 MSS aeronautic terminals in operation. This number is expected to grow to almost 72,000 in 2018, with almost half from the North American market. Maritime is expected to remain the most lucrative MSS market over the next 10 years. The sector contributed more than 35 percent of MSS industry wholesale revenues in 2009 and had the highest ARPU (Average Revenue Per User) among all MSS market segments. By 2018 it is expected that MSS maritime wholesale revenues will reach $768 million, despite the growing competition from maritime VSAT solutions. This growth

PAGE 20

Beam will be largely due to expanding ITC requirements from almost all types of maritime applications (such as ship operation, crew calling and safety communication), as well as the expected improvement of MSS market penetration (especially for MSS broadband service) leisure vessel and offshore sectors. A number of MSS operators are planning to launch new generation maritime services, and it is reported that the current market leader, Inmarsat, is evaluating the idea of generation satellite constellation.

Focus Taking Satellite Development To New HeightsSatellites play a crucial role in our lives, from global security and defense to local in-car navigation. On a daily basis we rely on them for telephone communication, television and radio reception, and long-range weather forecasting. Many of these satellites use operating platforms and payloads designed and built by Astrium, an expert in space applications for more than 40 years. Employing 15,000 men and women in France, Germany, the United Kingdom, Spain and the Netherlands, Astrium is a wholly owned subsidiary of EADS, a global leader in aerospace, defense and related services.by Tim Nichols, Siemens PLM SoftwareThe wide range of equipment that Astrium designs and manufactures includes solar generators; highly stable yet lightweight structures; thermal management systems and components; guidance, navigation and control processors; electrical, radio frequency and microwave key to the high standards of quality demanded for space and the timely delivery they expect. Glenn Harris, structural analysis engineer at Astrium, explains, We are always under pressure to meet development deadlines. A typical development cycle is one year and simulation represents six months of that. Astrium uses Siemens Femap element preand post-processor to optimize the simulation process within a concurrent engineering environment. Quickly getting to grips with complex designs In particular, Femap is used for the creation and analysis of the Eurostar telecommunications platform. This is split into two main units the Communications Module (CM) and the Service Module (SM). The CM portion usually has structures unique to a customers requirements, whereas the SM portion is common to many of Astriums Eurostar range of satellites. Harris points out, This structure lends itself to being new and re-used model data for each region, which SatMagazine May 201025

PAGE 26

joined together make up the full spacecraft design. Within each main portion of the satellite are numerous payload. The layers feature within Femap greatly aids Together with the use of the group function to identify nodes and elements in an area of interest, layers can be switched on and off to aid the understanding of complex regions. According to Harris, the data table is invaluable when the spacecraft structure is largely held together by cleats, which are generally modeled as spring elements. It is important for model quality that the nodes at either end of these springs are coincident, in this case that the springs are zero length. All the spring elements can be selected within the data table. By adding mass property, the lengths elements that are not zero length. A group can be made of these non-compliant elements for results to selections in the data table and to copy and paste this information into external spreadsheets has proved to be very useful. Easy Navigation, Modification + ImportThe Femap Application Programming Interface (API) has been used to develop the model and means work can easily be made to the model can be retained in the Siemens VisView software is used within Astrium to view Catia software VPM (Virtual Product Modeling) CAD data. An API routine is used to construct a model hierarchy in the same fashion as navigate to the chosen item and then import the CATIA V4 or V5 model directly into Femap using the API. Over the course of a project, this can reduce many modeling include one that creates multiple springs from single springs created by the Femap closest link command. Another routine enables the analyst to check that the rigid elements used as offsets from plates are orthogonal to the local coordinate system, which is required to avoid mechanisms. Yet another ranges in the model and writes this information to the data table. This allows additional modeling to be included with unique numbering. Focus Arabsat 5a SatMagazine May 201026

Using a routine that creates centerlines from sections imported from the CAD viewer, VisView enables the analyst to quickly locate heat pipes in the satellite solid mesh would require too high a mesh density for adequate results so this is avoided using the from imported solid CAD data. Individual dimensions can be transferred from VisView in the form of copied text, which is then referenced from the Windows Clipboard program by an API routine to generate a Femap point. The spacecraft mass distribution is applied to the model from a spreadsheet containing a standard Eurostar mass report. An API routine creates new worksheets by breaking the data into regions of point masses (CONM2) and non-structural mass (NSM) to be spread over elements. A second routine obtains initial mass and area data from the Femap model, uses the NSM information and updates the Femap model to match the new mass data. Harris describes the way in which Femap saves time during the post-processing of Nastran software create groups, which allow us to identify and correct the problems. We can view mode shapes and use strain energy contours to understand the nature of a structure and here the transparency function is very useful for looking inside a model. Spreadsheet CSV Nastran post-processing programs. These sort and provide margins of safety for the numerous load cases run on the spacecraft model. SatMagazine May 201027

PAGE 28

Concurrent Design, Analysis + SimulationAstrium uses Femap extensively for the iterative process of creating, checking, and viewing models, processing model results, and exploring alternatives. Harris notes, Having the ability to open several model databases at once allows a copy-and-paste approach to be employed. We can quickly generate new models by copying selected features from existing models. We can also copy and paste images and text into other documents and this speeds report writing. All the assistance that Femap provides Harris and his colleagues boils down to one imperative. We are working towards the date of the customer design review when we have to demonstrate a fully loaded design and prove the reserve capabilities, says Harris. Within this timeframe we have an initial requirement to deliver the completed model to the prime contractor for dynamic analysis for spacecraft/launch vehicle compatibility. The model will also be used by the Stress Department for static loading analysis to prove the design. Ideally we do not ever want to redo an analysis, but we often have to assume what the design changed we may need to iterate.

Whether pointing a dish at the sky, making a 2G or 3G mobile phone call, or connecting to a WiFi or WiMAX hub, its all about the magic of radio waves. And yet, until fairly recently, the three forms of wireless existed in separate silos, unable to make the connection.by Andrew Silberstein, Vice President and General Manager, Services, GlobecommAs urban and suburban markets have reached maturity around the world, mobile carriers are increasingly turning their attention to rural markets in the developed and developing worlds. This trend coincides with the realization among business executives that there is tremendous economic potential locked up in poor unleash it. Individuals may have low incomes, but they value communications highly and their cumulative demand can be substantial. Just ask the people at Tlcom sans Frontires, who began in 2004 to bring satellite phones to disaster areas and offer victims a free 3-minute phone call anywhere in the world. Satellite technology has become one of the keys for unlocking the rural market. Taking the place of terrestrial circuits, it can link base stations in the most remote locations imaginable. The challenge has always bandwidth to create a paying proposition for both customers and carriers. That challenge is being met in deployments around the globe. It requires the latest in dynamic bandwidth allocation technologies as well as a great deal of expertise in making otherwise incompatible protocols play well together. But from the Caribbean to Alaska,

In the US, the company wanted to extend its GSM coverage to areas with no backhaul infrastructure or affordable switching solution. In the Caribbean, they need to expand a CDMA handle backhaul and switching. For both problems, the answer was Globecomms SatCell. We provided satellite-linked base stations that connected through Globecomms teleport in Hauppauge, New York, to our state-of-the-art mobile switching platforms. Without major capital investment, the operator is now providing new subscribers with GSM and CDMA services, with 2G service and 3G capabilities including voice, voicemail, SMS, MMS, GPRS/EDGE, UMTS, prepaid and post-paid service, E911 Phase 2, CALEA the list goes on and on. When these GSM and CDMA subscribers hit this operators network, they are switched Digital Services In Rural GeorgiaThe business model that works in the Caribbean also works in rural Georgia. Many rural areas in the US are served by local carriers who face the challenge of keeping up with the digital revolution without the deep pockets of a national company. We helped one carrier there, which had a successful TDMA business and a GSM license, to start tapping roaming revenues. The high costs of a new GSM switch and gateways, plus the regulatory requirements affecting them, were high barriers to entry. My company was able to put them into the GSM business by hosting them on our state-ofthe-art GSM core switch and providing both terrestrial to the full digital capabilities of their hosted GSM network, the carrier now has a cost-effective forward path to LTE, the emerging wireless broadband standard, without the need to replace switching infrastructure in the future.Bringing Mobility To The VillageIn 2006, Alaskas leading integrated communications customers, whether they live in the states coastal cities or deep in its rugged interior. It was a striking vision: a single high-capacity, IP-based network serving all of General Communications (GCI) subscribers and capable of supporting the advanced data and video technology emerging from the laboratories of industry leaders such as Ericsson. We were asked to build a rural network serving 200 rural villages. Many of these sites are accessible only for six months of the year due to freezing temperatures and heavy snowfall. Bringing electricity to them, and keeping equipment warm through outages, were major issues. So was their location near the Arctic Circle. Satellites in GEO orbit have a tough time reaching so far north because of the curve of the earth. GCIs service area was right at the limit of territory that can be served via satellite. In fact, our planning assumed that the network would go down from time to time which does not comply with FCC E-911 regulations, nor maintain the all-important connection to the cellular home location registry (HLR) that authenticates roaming subscribers. The solution took a new approach to base station saving countless service calls. We equipped each base station with its own IP media gateway and HLR. The effect was to create a distributed switching system, in which each base station operates independently as well as interfacing with the core switch in Anchorage. If the satellite link goes down, local service continues, not only for those who make that area their home but also for Focus

SatMagazine May 201033roaming visitors. When the satellite link comes back up, the local media gateway restores long-distance service and re-synchs to the HLR at the core. In rural markets, communications can be more than a matter of convenience. One village customer of GCI went out hunting on his snowmobile, only to have it break down. The temperature was 30 degrees below zero and he was an hours walk from town. But he was able to call a friend who brought him a replacement part on another snowmobile. It probably saved his life.Wireless IP In ParadiseFor one of the largest mobile carriers serving the Caribbean and Central America, we have long functioned as their satellite guys. We have placed and small national markets throughout the region. But as the company expanded into countries with a bigger geographic territory, we suggested to them that SCPC was no longer the most appropriate answer. We proposed, instead, an all-IP demand-assigned TDMA network design. The reason? SCPC uses the dynamic bandwidth usage of a mobile network. Switching to demand-assignment would sharply reduce bandwidth requirements. The company was not thrilled at the idea, as they had experimented with a TDMA design from another company. The results were bad enough to make them swear off any technology but SCPC for satellite backhaul. We persisted putting a satellite link into the middle of is a perfect SCPC application. But if satellite is serving base stations in remote locations, trunking E1s is grossly you get your moneys worth from the link. Eventually, we persuaded them to try it. The results were two all-IP C-band networks in Central America, capable of voice, SMS and 3G data to the in-country hub, which would continue to use SCPC for the The design was actually a hybrid. In a TDMA design, the remotes share a pool of satellite bandwidth with the However, there is always the possibility that one or two of the circuits will get really busy and soak up most of the bandwidth, starving the other remotes. We designed any remote to an SCPC circuit. If one part of the service area is spectacularly successful, it would not bring down the whole network. Serving rural markets does, indeed, have its challenges. Reaching some sites in Central America required travel in a chartered plane and canoe, with a long walk at the end. At one site, our engineer was riding shotgun with a Cessna pilot when the plane overshot the runway. It went crashing into bushes and trees and stopped just ten feet short of a river. Our man was injured. What was he going to do? No plane, no hospital ended up he and the pilot hiked one hour to the site, completed the installation and waited until the next day for a plane to pick them up. We were extremely glad to get him back in one piece.About the authorAs Vice President and General Manager of Globecomms Services business, including cellular and global IPTV services, Mr. Silberstein plans and executes growth strategies, engages in strategic business development, as well as sales and execution of the companys on-going service contracts.

TInsighthe Global VSAT Forum is escalating a global effort to have public money earmarked for SATCOM projects. The opportunity has its roots in an international effort to bridge the digital divide; an increasing number of governments have established universal service funds (USFs) in which billions of dollars are now deposited for use in supporting communications projects. However, allocation of those funds is often delayed, or governments are unaware of the unique role that SATCOM services can play in enabling USF-supported projects.GVF has already taken action with respect to this opportunity. In July of 2009, GVF hosted a summit for USF directors with the Commonwealth Telecommunication Organisation. The event was held in Lusaka, Zambia. Directors of USFs from six African nations attended the meeting. The event was made possible through a GVF partnership with the US Agency for International Development (USAID). GVF has also been conducting bi-lateral meetings with other countries to explore their intentions with respect to USFs, and ongoing USF dialogues are currently underway in the Caribbean, Australia, Vietnam, and elsewhere. GVF is inviting broader Membership participation in the following areas of the USF Initiative:A white paper has been drafted by GVF legal counsel, Squire, Sanders & Dempsey, that provides background and insights into how GVF Members may approach the USF opportunity.

PAGE 35

The GVF Regulatory Working Group is developing USF Guidelines that will offer consensus-based policy guidance to USF directors. As many USFs are administered by regulatory agencies and in view of the enabling role of effective regulatory reform this will be modeled on the GVF Satellite Regulatory & Policy Guidelines, which have proven to be a very effective document among national administrations and intergovernmental groups. Complementary policy papers are envisioned on specific regulatory questions related to USFs, such as the importance of technological neutrality or the issues related to partnerships with foreign service providers. These and the aforementioned USF Guidelines will be used to build capacity in the regulatory community and to promote regulatory approaches that enable more successful mobilization and application of USF-supported satellite communications solutions.The GVF Regulatory Working Group welcomes broader participation from Members. The next steps for the initiative were discussed during a conference call that occurred earlier in April.

SatMagazine May 2010 Some of the worlds largest media organizations use BGAN worldwide. InsightThis steady rate of adoption is gratifying for Inmarsat and its Distribution Partners (DPs). Many of the worlds largest militaries, federal governments and mining companies in addition to elite broadcasters such as the BBC, CNN, Fox News and others have established the lightweight BGAN terminals as critical applications. To achieve this broad market penetration, Stratos and other Inmarsat DPs have expended a great deal of effort and creativity to address a variety of customer requirements. This includes bundling equipment and airtime with no capital investment, and offering starter plans with low usage allowances. Prospective customers also need the assurance that BGAN costs can be easily managed and that secure communications is guaranteed.Cost Control + High SecurityTo meet those objectives, customers carefully evaluate the value-added services from Stratos and other Inmarsat DPs. Within these offerings, customers seek tools to monitor airtime, restrict unauthorized usage and manage costs. The online Stratos Dashboard is an excellent example the product provides realfor voice and data, and the associated costs. Stratos Dashboard is fully automated and enables customers to activate SIM cards in minutes and modify service consumption per user or groups of users. high security options, easy VPN access, messaging services and full IP range. To ensure security for BGAN services, customers insist and the BGAN network. This feature, of which Stratos Trench is an example, provides additional security applications via an online, user-friendly interface. It also allows customers to block access to streaming services which can prevent unwanted high costs.Broadcasters Cite Reliable PerformanceNowhere is the need for reliable remote connectivity and security more pressing than in the broadcasting market. The worlds largest media organizations were BGANs early adopters. Today, they continue to use the service for live broadcast and store-andforward video clips from remote locations, or areas where communications infrastructure has been badly damaged. (BGAN was used extensively by major broadcast networks in Haiti, in the weeks following this years earthquake.)

More than ever portable, rapid-deploy solution. BGAN can be used for broadcast in remote parts of their territories, or in situations where a VSAT truck is not available or cannot be physically deployed. BGAN offers satellite communications in a form factor that is easy to deploy. It offers a reliable L-band solution that eliminates the need to coordinate VSAT connectivity, and provides the ability to be on the air harsh weather conditions. The premium BGAN X-Stream service, introduced early last year, offers a guaranteed minimum video streaming rate of 384 kbps, with streaming up to Insight

In February of this year, BBC News deployed BGAN X-Stream from Stratos to broadcast live coverage of Helen Skeltons record-breaking Amazon River video streaming from a remote location. In August of last year, BBC Northern Ireland deployed FleetBroadband from Stratos, the BGAN maritime equivalent, onboard the tall ship Bark Europa to Tall Ships Atlantic Challenge between Halifax and Belfast. For their time-critical data, the BBC, Fox News and other international broadcasters use Stratos GuaranteedAcces s to extend guaranteed bandwidth from the BGAN terminal through to the terrestrial infrastructure to the broadcast centers. Stratos GuaranteedAccess is enabled by StratosNexus a Stratos-managed Global Core network for traditional and IP-based services. Meeting The Connectivity Challenges For Remote Professionals become established as an ideal solution for remote professionals in the mining industry, where the need is growing rapidly for real-time information and extended require fast, dependable communications with operation centers in order to meet operating requirements and In the mining exploration phase, teams of geologists venture out to remote locations, often well beyond the take rock samples and gather data via BGAN, which needs to be analyzed to see whether there are valuable mineral deposits in the area. If the decision is made to construct a mine, the mining company uses BGAN to establish a communications infrastructure within minutes, expanding to aid the construction process until During the construction phase, BGAN is being used to liaise with contractors and suppliers. The service also can be used for telemedicine applications in the event of accidents or illnesses, and for voice communications between workers employed on different parts of the site. Creative applications, such as Stratos ChatCard Data service, can be used in conjunction with BGAN to provide an effective solution for personal calling enabling the remote workforce to stay in touch with friends and family back home. BGAN has been successfully deployed by Torontobased mining company Phoenix Geophysics where advantages include: the requirement of fewer people transmission of data; and savings in transportation costs. In Australia, surveying company Haines Surveys is using BGAN with great success during the exploration phase.

Overall, military users are in the midst of a paradigm shift to IP-based satcom solutions. The new Inmarsat mobile broadband services, such as BGAN and FleetBroadband, helped affect this shift by ensuring end-to-end, IP connectivity with high information security and encryption. Commanders appreciate that leading Inmarsat DPs such as Stratos have the terrestrial-connectivity capabilities to bring secure communications into the heart of military operations, regardless of whether they are in the USA, UK or Australia. To demonstrate the importance of offering leading edge technology to military agencies, Stratos recently signed agreements to distribute ruggedized BGAN terminals from ViaSat and Harris These provide customers with an affordable, high-performance military-rugged satellite solution.

With on-demand increasing in popularity in recent years, the challenge is also about ensuring that content is available as and when consumers want to view it. For broadcasters, used to playing out linear channels to a handful of platforms, the new multichannel, multi-platform environment has meant revisiting both the business and delivery models. Success will require flexibility and collaboration between broadcasters and broadcast services providers to ensure that consumers are provided with the content they want, on the platform of their choice.by Malcom Campbell Commercial Director, Broadcast Services (EMEA), Arqiva Satellite & MediaThe last decade has seen a revolution in viewing technology, and the pace of change in both consumer devices and broadcast technology is likely to accelerate. For broadcasters, used to playing out linear channels to a handful of platforms, the new multichannel, multi-platform environment has meant revisiting both the business and delivery models. Broadcast services providers have also had to develop new offerings that enable their clients to deliver content to multiple platforms, devices and, increasingly, create regions or territories. Barrie Woolston, Commercial Director, Arqiva Satellite & Media, explains that only by understanding how consumers will consume video in 2020, can broadcasters SatMagazine May 201043

SatMagazine May 201044 ensure that they dont miss out on future revenue opportunities. To do this, they need to work closely with their broadcast service suppliers to develop a next generation playout strategy that provides ingest, encoding, compression and packaging of linear, non-linear and on-demand content for distribution to the consumer.Todays Broadcast EnvironmentThe changing broadcast landscape in recent years has forced broadcasters to rethink their entire infrastructure, content and business strategies as consumers have demanded increasing volumes of video content, in more formats, to an increasing array of devices. With on-demand increasing in popularity in recent years, the challenge is also about ensuring that content is available as and when consumers want to view it. As a supplier of content services to broadcasters, Arqiva is able to obtain a close up view at what broadcasters want to do now. Increasingly, the Company is being asked to anticipate the future broadcast landscape to ensure that systems are being developed broadcasters will need not just next month puts Arqiva in a real position of responsibility, but also enables us to provide an insight into what the broadcast industry will look like in 2020. This article will focus on the two areas that will undergo radical change and which, Arqiva believes, will converge: playout and asset management. As well as being two areas of radical change, we also believe that they will be the key to successful management of future broadcast services. Why? Because some of the main drivers affecting how broadcasters distribute content reveals such is the case. They include...The continuous search for new revenue streams. A need to reach wider audiences, and, in many cases, with global reach will be required. An increased number of viable delivery mechanisms. Accelerating the search for efficiency and cost-effectiveness.The Broadcast Environment Of The FutureTo see how the broadcast world has changed, it is interesting to think about a typical channel on a large satellite network, such as BSkyB in the UK. Five years ago, most of these channels would just have been on the Sky DTH platform with no streaming web presence, and mobile TV considered as something for the future rather than a must-have viewing platform. Even the largest and best-funded channels would have been deployed on a maximum of three delivery mechanisms, with DTT and cable in addition to BSkyBs satellite network. Today, most channels will be streamed live on the web, and many channels are looking to distribute their output to other territories, generally via satellite, to serve either niche content audiences or expatriate communities in other countries and some broadcasters are planning for the near future when Ethernet-enabled set-top boxes (STBs) provide exciting new interactive revenue streams and open up truly global audiences. At the same time as this increase in complexity has occurred, broadcasters have also been looking very a trend that will continue and, its our belief, that this will mean that only the larger media groups will be able to cope with the cost and complexity of implementing the new systems, and the impact it will have on the culture SatBroadcasting

SatMagazine May 201045 of their organizations, required to take advantage of the new broadcast opportunities of the next decade. Thats not to say that smaller broadcasters cant take advantage of these opportunities but they will simply choose to outsource their playout and distribution, rather than building their own infrastructures. This makes it imperative that remote systems are designed that allow channel owners to outsource playout, control and functionality. As Arqiva peers into the future, noted is a mega trend that will affect every decision facing a broadcaster: the increasing fragmentation of broadcast audiences both by territory, platform, and demographic leading to pressure on broadcasters to provide content in multiple formats to protect [or take advantage of] advertising and subscription incomes and build new businesses in previously un-served territories. In this environment, broadcasters with access to content that people want to consume will increasingly use the following measures to increase revenues:Increase broadcast viewership by increasing the number of territories and languages served through broadcast distribution. Get much smarter about how to make new content using existing footage and do this at minimal cost. Increase the number of distribution methods through over the top (OTT), mobile, etc [growth of these products is expected to increase 55-fold between 2008 and 2014, reaching 58 million ].

Remote PlayoutRemote Playout and Distribution (RPAD) will be a critical consideration for broadcasters looking to deliver fully tailored television to multiple audiences speaking different languages across many regions and time zones. SatBroadcastingThe unique advantage of RPAD is that it allows a channel to be customized at the point of delivery to meet the exact requirements of a local audience, content owner or advertiser, including content replacement, tailored branding, time shifting and localized advertising, subtitling and voiceovers. Content is centrally stored in a secured main playout server, from where each tailored version is delivered through a managed IP network to the appropriate remote playout device for fully managed local broadcast. This will undoubtedly create new revenue opportunities for broadcasters/content owners through the sale of linear spot substitution advertising as a result of being able Figure 2: Schematic of typical operation of Arqiva RPAD

The television viewing experience will then be hampered, which of course, in the mind consuming and expensive.SMWhat initiatives has SUIRG been spearheading to reduce satellite interference?Martin Coleman Our main focus over recent years has been Carrier ID. If all satellite users have an ID assigned to them, and pinpoint which satellites they will be using, errors in operation are reduced and interference can be avoided. When interference does occur, it will be far easier to identify the source and, therefore, quicker to rectify, which will lead to less down-time for the broadcast affected. Three groups have been set up to deal with Video, Data, and VSAT.SMWhat technology and product innovations do you note that can help to reduce interference?

SatMagazine May 201056 The Royal Caribbeans Oasis of the Seas, the worlds largest cruise ship, has been equipped with MTN Satellite Communications (MTN) state-of-the-art VSAT satellite communications system. The 1,184foot (360.9-meter), 225,282-gross ton Oasis of the Seas carries up to 5,400 passengers and a crew of more than 2,000. The satellite communication requirements for such a massive ship presented special challenges.The communications suite is a critical component for operating the ship and its passenger services, said Max Schmidt, vice president of information technology, Royal Caribbean Cruises Ltd. We worked closely with MTNs engineering teams to develop a system that would be capable of supporting the unprecedented requirements of a ship this large and complex, with more than 2,700 passenger staterooms, dozens of dining and entertainment facilities and seven distinctly designed themed neighborhoods. There has never been a ship as grand, innovative and imaginative as the Oasis of the Seas. The seven themed neighborhoods include...

For the inaugural voyage of Oasis of the Seas, we supplied the highest bandwidth ever used on a single ship in the history of the cruise industry, said Brent Horwitz, senior vice president of MTN. The total bandwidth exceeded 26.6 Mbps, including 10 Mbps for Internet, 3 Mbps for voice and corporate data, 9 Mbps for an ABC live TV broadcast, 2 Mbps for video streaming, 1.5 Mbps for cellular phone service, and 1 Mbps for radio broadcasts and phones.A communications system was installed that uses two separate 2.4-meter stabilized C-band satellite antennas, which can simultaneously track two different satellites on MTNs global C-band network, with automatic beam switching to eliminate outages from satellite blockage, according to Horwitz. When crossing the Atlantic to its home port in Fort Lauderdale, the ships dual antennas with automatic beam switching technology, supported by our global shore network infrastructure, enabled the ship to transition seamlessly from one satellite footprint to another with no disruption of service, he said.

SatMagazine May 201062OmniGlobes decision to enter the satellite operations market is an integral part of its overall growth strategy and will consolidate its position as a leader in the provision of turnkey telecommunications services in remote Canadian markets. This logical step follows infrastructure ownership and operation, in addition to Canadian cellular spectrum licenses through the Companys partnership in Lynx Mobility. Vertical expansion into space-based infrastructure and spectrum is therefore a natural evolution. The primary motivation for securing increased access to space segment derives from the current lack of availability of ubiquitous Ka-band capacity serving Canada. This current supply shortage of openlyavailable Ka-band capacity is not the result of lack of innovation, nor motivation, in the Canadian market. In fact it is quite the opposite, with Canadian industry pioneering the commercial use of Ka-band frequencies demands from higher-bandwidth network services and the relatively high proportion of hard-to-reach rural Canadian residents, capacity is in high demand. Our focus has always been to develop the bestavailable technological solutions and to bring vital information and communications services to underserved markets throughout the globe, but the Canadian marketplace for satellite capacity is undersupplied and lacking in remote and rural commitment to ensuring that we have adequate spectrum to meet our customers present and future requirements. explained Jason Neale CEO of OmniGlobe.

The satellite program will be led by OmniGlobe Space Inc., a wholly owned subsidiary of OmniGlobe Networks, Inc. As part of this initiative, the company has appointed Julian Costley as Managing Director and Judy Harte as the Satellite Program Director. We are a leading player in a rapidly growing and dynamic market at a time when the next generation technological solutions are emerging and is therefore extremely well positioned to capitalize on this opportunity said Costley, an experienced entrepreneur and investor, himself previously founder and CEO of several highly successful international ventures in the telecommunications and investment sectors.Whats particularly exciting about CANUK-1 is that to serving Canada, said Harte, who brings over 25 Focus

Ka-band frequencies enable the use of much smaller regional coverage beams, known as spot beams.

Traditionally, Cand Ku-band satellite services have been favoured by enterprise and government users due to their perceived higher availability. This has historically been true and explains why most Ka-band capacity over North America is currently used for residential services. However, since the market introduction of DVB-S2 and the Adaptive Coding and Modulation (ACM) feature in particular, the technology now exists to maintain system Focusavailability by keeping the satellite link up, even in severe weather conditions. This has allowed Ka-band satellites to be deployed in support of enterprise users and private networks. OmniGlobe has consulted extensively with a diverse range of Canadian satellite service user groups, many of which are already OmniGlobe Networks customers today. In addition, OmniGlobe has analyzed extensive and detailed data sets representing the predominant residential segment of the Ka-band FSS market.

This market still convincingly supports OmniGlobes planned CANUK-1 satellite while allowing additional market space for future growth. Not only must affordable capacity be available, but it must be available in enough volume to make a difference in the marketplace, said Harte. OmniGlobe declined to comment in any detail on the it has received strong interest, both from its existing funding partners and also from the wider investment community as a whole. OmniGlobe did acknowledge that this was a larger initiative for them but drew attention to both their highly successful record of delivering new technology solutions and also their targets, year after year.Neale also added, In addition to the technical and management expertise of our internal team we also leverage the extensive experience of OmniGlobes Board, who have previously successfully delivered on many large initiatives while in senior leadership roles in some of the worlds largest telecommunications companies.As for the design and build of the spacecraft, OmniGlobe advised that it has had advanced discussions and extensive consultations with industry leaders within the international satellite manufacturing community. We have also had a very immediate and positive response to our recent press release announcing this initiative, said Harte, We are currently following up with many of the well known players in the wider satellite industry, on both the ground and space segment, to explore potential opportunities for collaboration. OmniGlobe will lead the design and manage the technological solutions for their lower cost Ka-band satellite in what they described as an increasingly competitive satellite manufacturing marketplace. Greater vertical integration up and down the value chain is happening right across the global satellite industry said Neale, In Ka-band, satellite services and operations are becoming intrinsically symbiotic; services need a secure supply of low-cost capacity, and high-volume mass-market capacity needs serviced and managed customers.

SM Why did you decide a move to SS/L was the correct step to take?Chris Hoeber I moved to SS/L almost 35 years ago, when it was Philco-Ford. I saw a relatively small organization that was very entrepreneurial and I saw an opportunity to get in at the beginning and make a difference. With 20-20 hindsight, I can tell you that I made the right decision at the correct time. After I had been at Philco for a year (it had then been renamed Aeroneutronic Ford), we won the Intelsat V Program and I joined the Systems Engineering team, responsible for the communications payload. Since that time, I have had the opportunity to contribute, at many levels, to SS/L becoming the player in the commercial satellite industry that it is today.

SM You worked at Hughes Space and Communications working on the 1G of domestic COMSATS. What was the impetus for your involvement in those programs?Chris Hoeber I left college in 1970 and my wife and I moved across the country to start a new life. To make a long story short, after we had settled into our apartment in southern California, my promised job fell through and I began knocking on every door within a 50 mile radius looking for work. I got an interview at Hughes in El Segundo and my interviewer arranged for a tour of the Hi Bay where I saw the prototype Intelsat IV spacecraft.I still remember coming home and saying, I fell in love with what I saw I know what I want to do. do that, I had to write an interpreter so that the brand new Hewlett Packard mini-computer could interpret HP Assembly language. The test computer had 16 K 16-bit words of memory and we communicated to it through a 10 bps teletype machine. The test job was perfect for me within a couple of years I had learned something about every aspect of the spacecraft design and operation. That knowledge, along with my natural curiosity, has provided the knowledge and experience that I have depended on for my entire career. SMWith 35 years of satellite industry experience, how different is the SATCOM world today than when you started your career? Where do you see our industry Chris HoeberSatellites have changed dramatically in the 35 years that I have been in the industry. They are much bigger and more powerful than they were in 1975 and they are much more capable. They are also much more reliable. As they are bigger and more powerful, they can do Executive Spotlight AsiaSat 5 completed and ready to load for shipping from SS/LImage courtesy of SS/L SatMagazine May 201070

many more things so the services that they deliver have In the late 1970s, satellites were used predominantly for telephony and broadcast television. Satellites broadcast only to huge ground stations that then delivered the signals to the television networks and to other organizations that further distributed the data. In the early 1990s, with the advent of Direct-to-Home (DTH) television, the paradigm changed so that satellites frequently broadcast directly to the consumer at their satellite technology which delivers information to mobile devices. Sirius XM Radio is a good example of this, as is our customer TerreStar, which has a satellite just now going into service that provides phone service to typical PDA-size phones that automatically switch from cellular signals to satellite when needed. Note that this is a complete reversal of the paradigm 35 years ago, eliminating the need to collect huge volumes of data in one location for redistribution on a local system.Todays advanced satellites can provide hundreds broadband services become more and more crucial as an enabler for economic growth, high throughput broadband satellites can deliver service to areas around the world where terrestrial broadband infrastructure is not available. Although I have described the different services that entertainment, we never forget that the ability to provide instantaneous communications services has much more important social implications including saving lives. SMResearch and Development is such a crucial arena for any company involved in the satellite industry millions of dollars are reserved for projects that are indicated as being critical for the companys growth. How do you determine in which direction such efforts should be extended?Chris Hoeber Each application, for example, DTH, has a service roadmap. We ask ourselves questions such as: What will be the impact of must-carry for local stations? What will be the impact of HDTV? What will be the impact of turning off analog over-the-air service? What will be the impact of IPTV? What will be the impact of 3DTV? Once weve done that, we go the next level, which is how do we design a spacecraft to meet those needs. Then we also have to consider the product line implications, for example to propulsion or antennas? After all of that kind of analysis, we decide what new developments need to be implemented. In parallel with the top down effort that I just described, our experts in hardware, such as propulsion and antennas, are telling us what is possible and what breakthroughs are around the corner. Often these pending breakthroughs stimulate the thinking of the systems folks and they come up with ideas that they couldnt have come up with on their own. The R&D process also includes some intuition and a huge amount of industry knowledge. As an industry Executive Spotlight SatMagazine May 201071

applications evolve. In order to produce great results once you have charted your course, you need to have world class experts with hundreds of individual skills, which we have at SS/L. At SS/L, we have an experienced and highly resourceful workforce with a passion for excellence, in a culture of open collaboration with our customers. I cant claim to be an expert in anything, except possibly satellite testing, but I am good at synthesizing solutions to problems by tapping into those areas of expertise. Our success shows that this process works.SMIn your world of R&D, what technological areas and investments are you looking toward to help boost SS/Ls competitiveness?Chris Hoeber First, we are right at the end of developing our next generation on board computer system which provides attitude control and command and data handling. This system will provide a new level of robustness and features that will be very attractive to our customers and which will help enable future advances in payload capability. Beyond that, we have a very broad array of developments going on. These include projects for Broadband, Mobile, Direct To Home Television and DARS Radio and they also provide trickle down capabilities to the core FSS business. SMSS/L has quite a history in the satellite industry from Courier MILSATCOMs to the 1300 series do you see more investment by government agencies in your product in the future? How will commercial satellites support government agency needs, due to various budget cutbacks?Chris Hoeber We recently announced that we are providing a propulsion system for a NASA lunar mission, and in late 2009, a Department of Defense Joint Capability Technology Demonstration (JCTD) was launched on one of our satellites. I think the line between government and commercial projects is beginning to blur and commercial processes will help provide best value solutions to the government. Personally, I dont like the term commercial. We have a product line with the same kind of natural evolution that you see in other industries. This process of constantly improving the product is much faster than funded programs can be. If you look at the computer industry think of the only 25 years or so ago. Before that time, computers had evolved in government labs with much more limited applications. There is no reason why the and reliability built into the product line concept for satellites, the same way they have for computers. There is a lot of interest in hosted payloads, such as the Cisco IP Router that we integrated onto Intelsat 14 and the navigation payload for the European Union that we are currently integrating onto a satellite we are building for SES. We expect there to be increasing demand for this kind of integration of government and commercial projects and we have the experience to Executive Spotlight SatMagazine May 201072

PAGE 73

SMHow will SS/L compete globally with the increased satellite manufacturing and launch contracts?Chris Hoeber This has always been a very competitive industry and we continue to believe that competition makes us better. SS/L builds the worlds largest and most powerful satellites, and we see increasing demand for larger satellites that help leverage the cost of a launch over more transponders. Large, powerful satellites also lend themselves well to the kind of multi-mission project that I mentioned previously, such as hosted payloads or condosats. Also, our long history of reliability is always in our favor when we compete for business.SMCould you tell us about the Mission Control Center in Palo Alto and how such plays into SS/Ls overall mission?Chris Hoeber We actually have four Mission Control Centers in Palo Alto capable of performing a number of missions in parallel. SS/L successfully launched, deployed and transitioned seven satellites in 2009 so our mission control group was very busy. We are particularly proud of our success in managing two launches that occurred on separate continents just 22 hours apart.On June 30, 2009 Sirius FM-5 was launched for SiriusXM Radio from Baikonur in Kazahkstan, followed by the TerreStar-1 launch for TerreStar Networks from the European Spaceport in Korou, French Guiana on July 1, 2009. The TerreStar-1 and Sirius FM-5 launches demonstrated the depth of resources and capability strength of the SS/L Mission Operations and launch crews. These control centers continue to provide service to our customers for the full life of the satellites that we provide, even if that lifetime is far greater than what the contract calls for. An On-Orbit Program Manager and Executive Spotlight SS/L resources, are available 24/7 for at least 15 years after a satellite is launched. SMWhat satellites is SS/L currently at work building? Are there any potential contracts we should know about to further our knowledge of your company?Chris Hoeber We currently have a backlog of 20 satellites and we have a number of active proposals. I cant tell you which ones we expect to win in the near term, but let me just say that in addition to launching seven satellites last year, we were awarded contracts to build seven new satellites. Were capable of taking on a new program on an average of once every six or seven weeks or so. I know that keeps us busy, but that is the way we like it. In recent years, I have focused a lot of my energies on recruiting, and I always look for college grads that have the same drive that I did 35 years ago. I tell them that, although I dont know the name of the satellite now, if they come to work for us they are likely to be assigned to a project and see it through to launch in two or three years. Its a great feeling to know that what you were working on last year is now providing an important service from 23,000 miles above the earths surface. That feeling is still what keeps me young. ` SatMagazine May 201073

Thank you, William.Usually the answer to that question is not a conscious decision. In the satellite business, some people would say we are very green. After all, other than when they are launched, thousands of satellites floating around in space are all running on solar power. No coal by-products, little fossil fuels being burned (just enough to keep them in orbit), no nuclear waste the sun is being used to generate power. This is so green; its hard to get any greener. G

PAGE 75

SatMagazine May 201075 Product UplinkWe in the satellite business can relax and go home, thinking we are saving our own little piece of the planet, correct?Wrong! Lets leave the launch side of the business for another day. What we want to discuss is the habit most of us have that causes harm to the environment we live in. Often deploying and operating VSAT antennas require the vehicles internal combustion engine running to produce the power. Apparently, we are in a business that requires us to operate our products in situations where we have no electrical outlets to plug into. Use of generators or vehicles is the most common solution in such cases, although not the most environmentally friendly. Products that are easy to use, safe, and environmentally friendly are being designed into every new C-COM product. National and International standards such as FCC, CE, and RoHS are part of quality objectives to our design teams. This ongoing commitment led C-COM to develop a solution which could prevent people from creating this non-green problem. Our clients were forced into situations where the production of CO2 (Carbon Dioxide) is a by-product of doing business. C-COM decided to become pro-active and provide a remedy for such a dependency and has designed, and now manufactures, a SolarPack solution that can eliminate the dependency on fossil fuels for powering the iNetVu line of mobile VSAT solutions. In keeping with the C-COM mission statement, we designed a cutting edge solution using the latest and best in class products to produce a solution that combines ease of operation and low maintenance at a very attractive price. The iNetVu SolarPack is offered in a neat compact package, containing all of the components required powering all of our antenna products from Flyway to vehicle mount platforms. The base unit contains a 100 amp hour battery, available in either a lead-acid or lithium choice, a charge control unit capable of handling output solar blankets (62 watts each), a 600 watt power inverter (which can handle most platform requirements) and all of the cables needed to connect the system. A number of manufacturers offer solar solutions, but often, the solutions have not been designed properly Figure 1: The iNetVu SolarPack System

SatMagazine May 201076 and consequently, do not work as intended. We have spent more than two man years developing and testing this solution; designing, prototyping, testing, modifying, re-building and re-testing, until we had a design that produced the results we expected. The iNetVu SolarPack can deliver 120 watts (with 2 solar blankets) of continuous power during daylight hours and then offer this same 120 watts of power for another 12 hours of darkness and keep this cycle going continuously. What if, you say, you need more power? Well, we simply add two more solar blankets to the system and 240 watts is attained. Still need more? You can connect a maximum of six solar blankets for a total of 340 watts of power. If this is still not enough, you can add another battery, which allows for the addition of two to six more solar blankets and now you can as much as 680 watts of continuous solar power. You can further expand the SolarPack to produce up to 680 watts of additional power. As long as you do not need to draw more than 600 watts of AC power from a single power plug, we have the solution for you. One may think that a portable generator can also perform the same operation more economically. Lets look at this statement in more detail. In order to verify this, we need to add up the total cost of your generator solution and compare it to our greener, solar solution.Lets make some assumptions and then do the math. If you have a nice reliable generator, say a Honda EU model that consumes about 2 gallons of petroleum per day, then the following table can be generated based on fuel prices in different countries. If we look at the # of Running Years per $5000 in Gas column, we can see that the ROI (Return On Investment) works out to as little as one year, depending on the country you live in. This is based on the SolarPack price minus the generator cost leaving you with about $5,000.00 to purchase petroleum. This does not take into consideration oil changes or the remedial or preventive maintenance that the generator will require to operate properly. Product Uplink

PAGE 77

SatMagazine May 201077 The cost to offset one ton of CO2 ranges from a low of $1.00 to a high of approximately $30.00. If we use an average cost of $15.00 per ton of CO2 then we can look at that cost as well. (Paradoxically, one gallon of gasoline produces 20 pounds of CO2.) http://www.fueleconomy.gov/Feg/co2.shtm lIf we are using approximately 2 gallons per day, we consume 730 gallons per year. For a larger (more than 1000 watts) unit, and one that is not accordingly. Therefore, such a solution will not only turn out to be expensive in the long run, but will also pollute the environment.Now that we have established that you should be using solar power and, in particular, the iNetVu SolarPack 1600 system, lets look at the type of batteries you should use. With the SolarPack, you have two choices. You can use traditional lead-acid or the newer type lithium batteries. The lead-acid battery can provide good power transfer, is fairly inexpensive, but there is a trade off against the number of charge cycles it can handle and it also weighs quite a bit. The lithium battery, on the other hand, is very light, can still operate below 80 percent capacity, and can deliver large amounts of energy than the lead-acid type. The following table shows the calculated run times for both the lead-acid and lithium batteries using a variety of load conditions. If you need Product Uplink more run time at a certain power level, you can add an additional battery pack, which will increase the run time by approximately 80 percent. The lead-acid battery we have chosen to use provides 100 amp hours of power assume NO power generation from the solar panels. After reviewing the run time statistics for the two different batteries offered with the iNetVu SolarPack solution, you may still not know which battery is the correct choice for you. There are some additional features that need to be considered. The table on the next page describes the operational parameters that must also be considered... Just to make sure you have all of the information you need, we would also like to provide a small comparison of the price difference between these two different battery solutions. If we create a real-world situation and then apply the costs to that situation, we can analyze the options in greater detail.

Based on these parameters, we will need to generate power from the batteries for 4 hours per day. If we check in the run time table we will see that the lithium battery can produce 4.92 hours of power at 250 watts and we can use a single battery to run for the 4 hours required. As this requirement will draw the battery down to near 100 percent discharge, the lithium can do 2,000 cycles before the battery has reached its expected life. That translates into 5 years and 5 months of usage, based on 7 days usage per week. If we do the same calculation using lead-acid batteries, the results are quite different. In order to provide 4 hours a day of power during absence of sun light, we would need 2 lead-acid batteries ( see table above). This current draw will discharge the batteries to near 100 percent of their power. The lead-acid battery can be discharged to 100 percent only 200 times before the battery becomes unusable. Product Uplink To maintain the 5 years of battery life, as in the case of the lithium battery above, we will need to replace both lead-acid batteries 9 times (once every 200 days). While the lead-acid battery costs approximately $500.00 each, over 5 years, it will cost $9,000 to replace lead-acid batteries (2 batteries to replace 9 times) using the above described scenario. The lithium battery will only cost $3,000 and will not need to be replaced during its 5 years of usage. As with any technology, a decision should be based on these facts. When all the facts are known about a solarbased solution, it becomes clear that not only is it a green solution, but it can be a very practical solution as well. Before you buy, ask the tough questions, get the correct answers, verify the answers and enjoy your power without the monthly bills.About the authorPaul Seguin is a Satellite Application Specialist with C-COM Satellite System Inc.

In the race to compete with industry peers, wireless services and terrestrial capacity, service providers and operators must constantly look to improve bandwidth use and user throughput to stay ahead.

This is so green its hard to get any greener.Intro To Adaptive Coding + Modulation (ACM)Adaptive Coding and Modulation is a statistical, non-static advantage that enables dynamic changes in are not guaranteed, but are predictable. ACM technology converts link margin to an increase in the data throughput of satellite links. Only non-synchronous data networks (such as Ethernet packet-based networks) can take advantage of a dynamic data throughput rate. All satellite links are designed to function at a certain annual availability. The closer to 100 percent we demand of our link availability, the more link margin we need to meet this demand. Figure 1 on the following page is a graph of availability vs. link margin of a Ku-band link from Germany to Nigeria. A change in guaranteed annual availability from 99.8 percent to 99.6 percent (as little as 0.2 percent per year) equates to 17.5 hours per year (365 Day 24hours/day .002 = 17.5 Hours). In Figure 1 it can be seen these 17.5 hours/year demands or saves 2.5 dB of link margin. This means someone who requires 99.8 percent availability instead of 99.6 percent availability would need to factor an additional 2.5 dB of link margin for the entire year. Conversely, deciding to run this link with 99.6 percent availability would save 2.5 dB of link margin for the

entire year. Different links have different link margin requirements. Consider a C-band link between Italy and China with very different link availability characteristics. In Figure 2, you can clearly see that the same change from 99.6 percent availability to 99.8 percent availability requires a mere 0.35 dB of additional link margin.Rain fade, inclined orbit satellite operation, antenna pointing errors, noise and interference can all degrade satellite link conditions. All of these conditions determine the overall link margin of a system. Because ACM converts Tech Channel

SatMagazine May 201083 link margin to additional user throughput, it can be clearly seen that the greater of ACM. As link margin is reduced, so too is the value of ACM. It can also be stated that as guaranteed availability is increased, link margin will also need to be increased. Conversely, as availability requirements are reduced, link margin will also be reduced and the value of ACM will therefore be reduced.Intro To Double Talk Carrier in CarrierUnlike ACM, DoubleTalk Carrier-inCarrier technology is a calculable, Carrier-in-Carrier is based on Applied Signal Technology s DoubleTalk bandwidth compression technology. DoubleTalk uses Adaptive Cancellation, a patented technology that allows the transmit and receive carriers of a fullduplex satellite link to be transmitted in the same transponder space. When combined with advanced forward error correction and modulation techniques, DoubleTalk Carrier-in-Carrier can deliver unprecedented operating expense savings. In addition to operating expense (OPEX) savings, DoubleTalk Carrierin-Carrier can also provide capital expenditure (CAPEX) savings by allowing a smaller BUC/HPA and/or antenna.Figure 3 shows a conventional full-duplex satellite link, where two carriers are adjacent to each other and centered and different frequencies. Figure 4 shows the typical DoubleTalk Carrier-in-Carrier operation, where the two carriers are centered at the same frequency, thus sharing the same spectrum. When observed over a spectrum analyzer, only the Composite is visible. Carrier 1 and Carrier 2 are shown in Figure 4 for reference only. DoubleTalk Carrier-in-Carrier is complementary to all advances in modem technology, including advanced FEC and modulation techniques. As these technologies approach theoretical limits of power and bandwidth advanced signal processing techniques) provides a new Tech Channel Figure 3: Conventional Full-Duplex Satellite Link Figure 4: Duplex Link with DoubleTalk Carrier-in-Carrier

For example, DoubleTalk Carrierin-Carrier when used with 16-QAM approaches the As DoubleTalk Carrier-in-Carrier allows equivalent or FEC code, it can simultaneously reduce CAPEX by allowing a smaller BUC/HPA and/or antenna. DoubleTalk Carrier-in-Carrier can be used to save transponder bandwidth and/or transponder power, thereby allowing successful deployment in bandwidthlimited as well as power-limited scenarios.Case StudiesUsing the highly regarded Intelsat Lease Transmission Plan Program (LST) link budget tool and actual Intelsat satellites, we have run four (4) satellite link budget scenarios. For the purpose of this exercise, all links in scenarios 1-3 require a duplex guaranteed minimum 10 Mbps data rate. All calculations are made using only DVB-S2 modulation and coding combinations to ensure there is no confusion between link budget operational BW (= SR 1.27). Scenario 4 is a special case study Note that in all of the scenarios, link margin remains consistent within each scenario. Link margin is directly related to link availability and therefore it follows that link margin remains consistent when doing a true comparison of technologies, weather you are running a conventional link, conventional link with ACM, Carrierin-Carrier, or Carrier-in-Carrier with ACM.Definitions[1] Occupied BW: This is the bandwidth that the carrier(s) actually occupy on the satellite. For conventional links, the occupied BW is equal to the Symbol Rate of the carrier times one plus the filter figure (Occupied BW = 1.27 SR). In CnC links, when the carriers have equal symbol rates, we show the Occupied BW as (x.xx/2) because two carriers are using the same physical BW. Note, regardless of rolloff or filter figures used, all comparisons will equally benefit or suffer by the same percentage. This is a true comparison of technologies, not a misleading comparison using dissimilar criteria.[2] Threshold Mod/Cod: In conventional links, this is the most spectrally efficient Mod/Cod with a QEF performance Es/No that is at or BELOW the Threshold Es/No for the link. In CnC carriers, the Threshold Mod/Cod must be the most spectrally efficient Mod/Cod with a QEF performance Es/No + CnC Es/No Penalty that is at or BELOW the Threshold Es/No for the link.[3] CnC Es/No Penalty: This is the undesired penalty that must be added to the Threshold Es/ No to determine the Threshold Mod/Cod that can be used when running CnC link budgets. [4] Threshold Es/No Req: This is the worst case Es/No (most faded condition) the link will experience to accommodate the availability of the link. The Threshold Es/No will be negatively impacted (lower) when Link Availability is increased 99.8 percent -> 99.9 percent and will be higher when Link Availability is decreased 99.9 percent -> 99.8 percent.

SatMagazine May 201085 [5] Clear Sky Es/No: This is the best Es/No value (least faded condition) the link will ever experience with the given satellite, earth station equipment, weather conditions etc. [6] Link Margin: This is the difference between the Clear Sky Es/No and the Threshold Es/No. This is essentially the maximum delta in dB between best and worst case fade conditions. [7] Total Allocated BW: In conventional links this is the sum of the Occupied BW of Link A to B and Link B to A. In CnC links, this is the larger of the two carriers, or if the carriers are the same size it is the sum of the Occupied BW of Link A to B divided by 2. A satellite operator will charge for the larger of either Total Allocated BW or Total PEB. [8] Total PEB BW: Total Power Equivalent Bandwidth (PEB) relates to the amount of total power used by the carriers represented as a bandwidth equivalent. A satellite operator will charge for the larger of either Total Allocated BW or Total PEB. [9] Clear Sky Mod/Cod A to B: In conventional links, this is the most spectrally efficient Mod/ Cod with a QEF performance Es/No that is at or below the Clear Sky Es/No for the link A to B. In CnC carriers, it is the most spectrally efficient Mod/Cod with a QEF performance Es/No + CnC Es/No Penalty that is at or below the Clear Sky Es/No for the link A to B. [10] ACM Max DR A to B: This is the maximum data rate achievable in clear sky conditions. This is calculated by multiplying the Clear Sky Mod/Cod A to B spectral efficiency with link A to B symbol rate or: Clear Sky Mod/Cod A to B spectral efficiency with (link A to B Occupied BW / 1.27). [11] Clear Sky Mod/Cod B to A: In conventional links, this is the most spectrally efficient Mod/ Cod with a QEF performance Es/No that is at or below the Clear Sky Es/No for the link B to A. In CnC carriers, it is the most spectrally efficient Mod/Cod with a QEF performance Es/No + CnC Es/No Penalty that is at or below the Clear Sky Es/No for the link B to A. [12] ACM Max DR B to A: This is the maximum data rate achievable in clear sky conditions. This is calculated by multiplying the Clear Sky Mod/Cod B to A spectral efficiency with link B to A symbol rate or: Clear Sky Mod/Cod A to B spectral efficiency with (link A to B Occupied BW / 1.27) [13] Total DR Increase Percent: This is the difference between the minimum guaranteed DR (10 Mbps *2 = 20 Mbps) and the sum of ACM Max DR A to B and ACM Max DR B to A as a percentage. [14] Summary Section: BW/PEB is the greater of Total Allocated BW or Total Power Equivalent BW (its what the satellite operator will base the per Hz price on).

SatMagazine May 201088 Scenario 1 circuit. Synchronous circuits and synchronous data interfaces, such as G.703, RS422 and V.35, do not allow for variances in data rate once the circuit is established. They are static in throughput and have strict clocking and timing requirements. For this reason, a statistical and dynamic technology such as ACM cannot be used in these types of circuits and provides no value regardless of the available link margin. As discussed earlier, Carrier-in-Carrier is a static technology that provides an unchanging advantage and proves to be of substantial value in synchronous circuits. As seen in the Scenario 1 summary section, CnC without ACM provides a 32.5 percent BW/PEB savings over a conventional link. In all other scenarios, the result is either unimproved or not applicable. Financially Speaking: Assuming a cost per MHz of BW/PEB is $3000.00 USD per month, a service provider could save $975/MHz (14.12 9.52) = $4,485 per month or $53,820 per year by deploying CnC on this circuit. Scenario 2 Guaranteed minimum 10 Mbps SLA duplex link Determine the best overall modulation technique when considering: (1) Asynchronous, packet-based Data, 2) Link 99.65 percent availability, and 3) Typical Ku-band rain fade conditions.In Scenario 2, we can see that packet-based networks (when combined with ACM) can yield a higher data throughput. In this scenario, however, due to the 99.65 percent Link Availability chosen (vs. 99.85 percent in scenario 1), the link margin needed is only about 1.5 dB. Due to this lower link margin, we see only a minimal (18.5 percent) increase in data throughput due to ACM alone. As shown in the column CnC with ACM (Reduced BW), Carrier-in-Carrier offers a 32.2 percent savings in allocated bandwidth, plus an 11.0 percent increase in data throughput due to ACM. Financially Speaking : Assuming a cost per MHz of BW/PEB is $3000.00 USD per month, a service provider could save $966/MHz (10.4 7.05) = $3,236 per month or $38,833 per year by deploying CnC and would increase user throughput by an additional 2.2 Mbps for the majority of the year. What happens if we convert the savings in bandwidth to additional throughput? As seen in the CnC with ACM (Max Throughput) column of the Summary section, a user could choose to convert BW savings into additional throughput by running a 10.4 MHz CnC link (equivalent to the Scenario 2a Total allocated BW). Even in the most highly faded condition, running 8-PSK 3/5 Mod/ Cod, CnC alone would give the user 29.5 Mbps of capacity (14.7 Mbps each way). This is a 47.5 percent increase over the 20 Mbps guaranteed SLA. CnC, without ACM, in a highly faded link condition provides a 29 percent throughput advantage over ACM in CLEAR SKY CONDITIONS! When clear sky conditions do arise, CnC with ACM will run at Mod/Cod 8-PSK 2/3 offering 32.7 Mbps of capacity (16.3 Mbps each way). This is 63.5 percent percent better than ACM alone. As we are running a BW limited link (being charged by BW not by PEB or power), we know that the cost per month for the CnC 10.4 MHz is the same as the Conventional (non CnC) 10.4 MHz and we have now increased our Data Rate capacity by up to 63.5 percent over our SLA. When looking at all available options, it is clear that CnC combined with ACM provides the best overall result. Scenario 3 (next page) Guaranteed minimum 10 Mbps SLA duplex link Determining the best overall modulation technique when considering: 1) Asynchronous, packet-based, Data Link, 2) 99.7 percent availability, and 3) Ku-band rain fade conditions in severe rain fade locations.

SatMagazine May 201090 In Scenario 3 we see that packet-based networks running ACM can improve data throughput by a Availability, Ku-band operation, and a combination of geographical locations that experience severe fade conditions creates a Link Margin demand of 6.9 to 8.1 dB. Due to this high link margin, we see substantial (78.5 percent) increase in data throughput due to ACM alone.Carrier in Carrier offers a 28.8 percent savings in allocated bandwidth combined with a 96.5 percent increase in data throughput due to ACM as seen in the CnC with ACM (Reduced BW) column. It can be seen in this scenario the increase in data rate due to ACM was slightly higher in the CnC with ACM (Reduced BW) circuit than in the ACM only circuit (96.5 percent vs. 78.5 percent). The reason for this is quite simple. The Link margin of 6.9 dB (scenario 3a Link B to A) available in clear sky conditions far exceeded the most and, therefore, could not be further converted to increased capacity. This is another advantage of using Tech ChannelCnC technology in combination with ACM. In virtually all CnC circuits a lower mod/cod can be used as we are spreading the signal, requiring a lower Es/No but over a larger occupied BW. As can be seen in the graph below, when you can attain your minimum SLA by using a mod/cod that requires a lower Es/No, more link margin can be converted to user throughput. Furthermore, as you can see in the Ideal spectral change in Es/No, there is roughly an increase of 1.6 5dB of link margin, in an ideal DVB-S2 implementation, throughput should increase by 60 to 80 percent regardless of where you begin (Threshold Es/No). Financially Speaking : Assuming a cost per MHz of BW/PEB is $3000.00 USD per month, a service provider could save $864/MHz (10.58 7.53) = $2,635 per month or $31,622 per year by deploying CnC and would increase user throughput by an additional 19.3 Mbps for the majority of the year.

PAGE 92

SatMagazine May 201092 As we have done in Scenario 2, lets see what happens if we convert the savings in bandwidth to additional throughput. In Scenario 3, the CnC link is power limited, running a 7.05 MHz carrier is equivalent to using 7.53 MHz PEB. For this reason, we need to compare a 9.9 MHz (Total Allocated BW) CnC link equating to a 10.58 MHz BW/PEB, as this will give us a realistic equivalent satellite cost. As seen in the CnC with ACM (Max Throughput) column of the Summary section, a user could choose to convert BW savings into additional throughput by running a 9.9 MHz CnC link. In the most highly faded condition, running 8-PSK 3/5 Mod/Cod in both directions, CnC alone would give the user 28.0 Mbps of capacity (14.0 Mbps each way). This is a 40.0 percent increase over the 20 Mbps guaranteed SLA even in the most faded of conditions (where ACM will provide little to no value). When clear sky conditions do arise, CnC with ACM will run at Mod/Cod 32-APSK in one direction and 16-APSK 5/6 in the opposite direction offering 55.1 Mbps of capacity (29.2 Mbps A to B, 25.9 Mbps B to A). Mbps and 96.5 percent better than ACM alone. Again, it is clear that DoubleTalk Carrier-in-Carrier combined with ACM provides the best overall result. Scenario 4 (E3 Link Optimization) E3 (34.368 Determine the best overall modulation technique when considering: (1) synchronous 34.368 Mbps E3 data, (2) 99.95 percent link availability, and (3) Typical Ku-band rain fade conditions. Scenario 4, as with scenario 1 conventional synchronous circuit. E3 circuits and synchronous data interfaces, such as G.703 do not allow for variances in data rate once the circuit is established. They are static in throughput and have strict clocking and timing requirements. For this reason, a statistical and dynamic technology such as ACM cannot be used in these types of circuits and provides no value regardless of the available link margin. Carrieradvantage and proves to be of substantial value in E3 circuits. As seen in the Scenario 4 summary section, CnC without ACM provides a 32.5 percent BW/PEB savings over a conventional link. In all other scenarios, the result is either unimproved or not applicable.Financially Speaking: Assuming a cost per MHz of BW/PEB is $3000.00 USD per month, a service provider could save $975/MHz (48.50 32.73) = $15,375 per month or $184,500 per year by deploying CnC on this circuit.ConclusionWhen considering bandwidth conservation, user data throughput maximization or a combination of the two, there are many choices and technologies available. Synchronous, packet-based circuits can be improved by ACM, but these improvements are even more substantial when a combination of ACM and Carrierin-Carrier technologies are deployed.
