CCIA Comments in ITU CWG-Internet OTT Open Consultation.Pdf
CCIA Response to the Open Consultation of the ITU Council Working Group on International Internet-related Public Policy Issues (CWG-Internet) on the “Public Policy considerations for OTTs” Summary. The Computer & Communications Industry Association welcomes this opportunity to present the views of the tech sector to the ITU’s Open Consultation of the CWG-Internet on the “Public Policy considerations for OTTs”.1 CCIA acknowledges the ITU’s expertise in the areas of international, technical standards development and spectrum coordination and its ambition to help improve access to ICTs to underserved communities worldwide. We remain supporters of the ITU’s important work within its current mandate and remit; however, we strongly oppose expanding the ITU’s work program to include Internet and content-related issues and Internet-enabled applications that are well beyond its mandate and core competencies. Furthermore, such an expansion would regrettably divert the ITU’s resources away from its globally-recognized core competencies. The Internet is an unparalleled engine of economic growth enabling commerce, social development and freedom of expression. Recent research notes the vast economic and societal benefits from Rich Interaction Applications (RIAs), a term that refers to applications that facilitate “rich interaction” such as photo/video sharing, money transferring, in-app gaming, location sharing, translation, and chat among individuals, groups and enterprises.2 Global GDP has increased US$5.6 trillion for every ten percent increase in the usage of RIAs across 164 countries over 16 years (2000 to 2015).3 However, these economic and societal benefits are at risk if RIAs are subjected to sweeping regulations. -
Low-Cost Wireless Internet System for Rural India Using Geosynchronous Satellite in an Inclined Orbit
Low-cost Wireless Internet System for Rural India using Geosynchronous Satellite in an Inclined Orbit Karan Desai Thesis submitted to the faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science In Electrical Engineering Timothy Pratt, Chair Jeffrey H. Reed J. Michael Ruohoniemi April 28, 2011 Blacksburg, Virginia Keywords: Internet, Low-cost, Rural Communication, Wireless, Geostationary Satellite, Inclined Orbit Copyright 2011, Karan Desai Low-cost Wireless Internet System for Rural India using Geosynchronous Satellite in an Inclined Orbit Karan Desai ABSTRACT Providing affordable Internet access to rural populations in large developing countries to aid economic and social progress, using various non-conventional techniques has been a topic of active research recently. The main obstacle in providing fiber-optic based terrestrial Internet links to remote villages is the cost involved in laying the cable network and disproportionately low rate of return on investment due to low density of paid users. The conventional alternative to this is providing Internet access using geostationary satellite links, which can prove commercially infeasible in predominantly cost-driven rural markets in developing economies like India or China due to high access cost per user. A low-cost derivative of the conventional satellite-based Internet access system can be developed by utilizing an aging geostationary satellite nearing the end of its active life, allowing it to enter an inclined geosynchronous orbit by limiting station keeping to only east-west maneuvers to save fuel. Eliminating the need for individual satellite receiver modules by using one centrally located earth station per village and providing last mile connectivity using Wi-Fi can further reduce the access cost per user. -

Echostar Annual Report Year Ended December 31, 2012 March 20, 2013
NASDAQ: SATS 100 Inverness Terrace East Englewood, CO 80112 303.706.4000 | echostar.com EchoStar Annual Report Year Ended December 31, 2012 March 20, 2013 Dear EchoStar Corporation Shareholders; 2012 was a very busy year for EchoStar. One of the most exciting accomplishments for 2012 was the addition of two new satellites to our growing fleet through the successful launches of EchoStar XVI and EchoStar XVII, bringing our total number of owned, leased and managed spacecraft to twenty-two. EchoStar operates the world’s fourth largest commercial geostationary satellite fleet and we continue to solidify our position as a premier global leader in satellite communications and operations. EchoStar ended 2012 with revenue of $3.1 billion, a growth of 13% over 2011. EBITDA in 2012 was $794 million, a growth of 64% over 2011. We generated a healthy $508 million of cash from operating activities in 2012 as a result primarily of the strong net income in 2012 and ended the year with a strong balance sheet with $1.5 billion of cash and marketable securities. EchoStar reached two very important long-term North America goals in 2012 with the market implementation of the HughesNet Gen4 service and the roll-out of the Hopper Whole Home DVR solution for DISH. Both solutions are garnering high praise and rapid adoption by consumers, a glowing testament to the capabilities and ingenuity of the EchoStar team. Additional notable accomplishments for 2012 include the very successful introduction of two new Slingbox retail products, several large enterprise contract renewals and new customers for Hughes data network services around the globe, and above-forecast sales of set-top-box products and video services to our established operator customers. -
Photo Release -- Space Systems/Loral-Built Telstar 11N Satellite on Track with Post Launch Maneuvers
Photo Release -- Space Systems/Loral-Built Telstar 11N Satellite On Track With Post Launch Maneuvers Solar Arrays Deployed On Schedule Following Successful Launch PALO ALTO, Calif., Feb 27, 2009 (GlobeNewswire via COMTEX News Network) -- Space Systems/Loral (SS/L), a subsidiary of Loral Space & Communications (Nasdaq:LORL) and the leading provider of commercial satellites, today announced that the Telstar 11N satellite built for Telesat, one of the world's leading fixed satellite services operators, is performing post launch maneuvers according to plan. The satellite's solar arrays deployed on schedule several hours after separation, following yesterday's successful launch aboard a Zenit-3SLB rocket from the Baikonur Space Center in Kazakhstan. Tomorrow the satellite will begin firing its thrusters to maneuver into its final geosynchronous orbit. A photo accompanying this release is available at http://www.globenewswire.com/newsroom/prs/?pkgid=5941 "We are proud to know that this high-power satellite will help make information and entertainment more accessible around the world," said John Celli, President and Chief Operating Officer of Space Systems/Loral. "Telstar 11N demonstrates the flexibility of our standard 1300 satellite platform, which in this case was engineered to accommodate a smaller launch vehicle. It is this flexibility together with long term proven reliability that have helped SS/L achieve more than 40 percent market share over the past five years." When it reaches its final geosynchronous orbit, Telstar 11N will support video and data applications in North America, Western Europe, and Africa. Space Systems/Loral designed the satellite with a unique Atlantic Ocean beam, which will help Telesat meet growing demand for mobile broadband from both commercial and government customers in shipping and aviation. -
