O3b Networks, Ltd. is a network communications service provider building a medium Earth orbit satellite constellation. The network will combine the relatively large reach of satellite with high speed and medium latency to deliver satellite Internet services and mobile backhaul services to emerging markets. The company was founded by Greg Wyler in 2007. The name "O3b" stands for "() Other 3 Billion", referring to the population of the world where broadband Internet is not available without help. O3b is financially backed by SES, Google, HSBC, Liberty Global, Allen & Company, Northbridge Venture Partners, Soroof International, Development Bank of Southern Africa, Sofina and Satya Capital. After initially planning to launch in 2010, on June 25, 2013, O3b launched the first four of an initial constellation of 8 satellites into orbit. A further four satellites were launched in December 2014. O3b will primarily serve mobile operators and Internet service providers, providing for voice and data. The network will consist of eight Ka-based satellites orbiting at an altitude of 8,000 km, which is less than one quarter of the altitude of geostationary satellites; significantly reducing satellite latency. ==Status== Operators in the Cook Islands,〔() O3b Networks and Telecom Cook Islands Sign Long Term Agreement on Bandwidth Provision for Internet Connectivity〕 Pakistan〔Interactive e-solutions signs exclusive national capacity agreement with O3b Networks to deploy high-speed internet to Pakistan〕 and Nigeria〔() O3b Networks signs deal with Netcom, Nigeria to provide fast and reliable connectivity to ships and offshore platforms〕 have recently prebooked capacity on the O3b constellation to serve their respective markets. O3b also announced the selection of Europe Media Port (EMP)〔() O3b Selects Europe Media Port (EMP) as its First Gateway Teleport Operator for New High Capacity Data Network〕 the world’s fastest growing teleport in 2009 according to the World Teleport Association – to be the first provider of Gateway Teleport services for O3b’s global network. O3b also announced a contract with ViaSat for the production and installation of Ka-band infrastructure indicating significant progress in the deployment of O3b’s Next Generation Network. The value of the ViaSat contract is approximately $47 million.〔()〕 The company has recently had a change of CEO once financial closure had been obtained.

In November 2014, MS Quantum of the Seas became the first cruise ship to provide fast internet to guests through O3b Networks. The service was branded "Voom" by its cruise line, Royal Caribbean International and is being rolled out to all ships in the future. () () In August 2015 SES subsidiary, SES Government Solutions agreed a one-year contract with US government scientific agency, NOAA (National Oceanic and Atmospheric Administration) to supply O3b services and ground equipment to the National Weather Service Office in American Samoa, which will expand NOAA's broadband connectivity outside the continental US to provide weather, water, and climate data, and forecasts and warnings to American Samoa. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「O3b Networks」の詳細全文を読む スポンサード リンク
