Broadband Global Area Network
Broadband Global Area Network (BGAN, formerly RBGAN, which stood for Regional Broadband Global Area Network ) is a mobile service for broadband internet access and telephony from the satellite operator Inmarsat .
Technology and operation
An Internet connection with up to 492 kbit / s is possible with a BGAN satellite modem, and all data terminals offer connection options for telephones.
At the beginning, the service as an RBGAN was handled exclusively via the Thuraya satellite. From mid-2005 the connection was made via the new Inmarsat-4 satellite over the Indian Ocean. This also introduced the higher-quality service BGAN and deleted the R from RBGAN. RBGAN was discontinued on December 31, 2008. The RBGAN modems used up to then became worthless.
In mid-2006 the second Inmarsat-4 satellite went into operation. In addition to Europe, Africa, Asia and the Middle East, the entire American continent was covered. On August 18, 2008, the third I-4 Americas satellite was successfully launched from the Baikonur spaceport . After its commissioning and a repositioning of the entire I-4 fleet, BGAN became available worldwide on February 24, 2009.
In 2012 it was planned that the BGAN service would remain in operation until around 2020.
