Extending Inmarsat BGAN to Efficiently Support the 3GPP Multimedia Broadcast/Multicast Service

Inmarsat’s BGAN System operates over the Inmarsat-4 satellites, which are among the largest commercial geostationary satellites in service today. The first two Inmarsat-4 satellites were launched in 2005. Each satellite supports over 200 spot beams, and once fully deployed, the constellation of the three Inmarsat-4 satellites will provide continuous global coverage for Inmarsat services up to 80 degrees latitude.
