Inmarsat Broadband Global Area Network (BGAN) |
||||||||||||||||||||||||||||||||||||||||||||||||||||||
The launch of BGAN - Inmarsat's Broadband Global Area Network service – has marked an important milestone in telecommunications history. Commercial service introduction in December 2005 heralded the first combined voice and high-speed data service available anywhere on the planet via a highly portable device. It surpasses anything else currently available for those working or travelling in locations without a reliable telecoms infrastructure. BGAN provides network access at speeds of up to 492kbps. It also offers guaranteed data rates on demand up to 256kbps. Commercial service was launched last December on the first of three satellites that will provide BGAN service. Inmarsat is launching commercial BGAN service via the Inmarsat-4 F2 satellite on 17 April 2006. In addition to the Americas, coverage will extend to the portion of Western Africa that lost regional BGAN coverage during the July 2005 service migration. When the complete satellite constellation is deployed in 2007, these powerful new satellites will provide voice and high-speed data services globally, except the polar caps and some parts of the Pacific Ocean region. Two service classes – a “background” IP class, over a shared channel and a “streaming” IP class, which will offer guaranteed data rates of up to 256Kbps – will be offered as part of the BGAN service.

BGAN Satellite Terminals Hughes Network Systems (HNS) 9201 Over a standard IP connection, it connects at up to 492kbps, while guaranteed data rates range from 32kbps to 256kbps for both send and receive. The HNS 9201 is the only terminal in the range to feature both a dedicated 64kbps ISDN data channel and connection via WiFi, in addition to USB and Ethernet. Voice is delivered via an ISDN handset. Nera WorldPro 1000 Over a standard IP connection, it connects at up to 384kbps in the receive direction, and up 240kbps when sending. Streaming data is available at 32kbps and 64kbps for both send and receive. The terminal connects to a laptop computer via a USB port or over a Bluetooth wireless connection. The unique feature of the Nera WorldPro 1000 is its separate antenna, attached by cable, which allows the user to position the antenna on a window sill while working indoors. Voice is via a custom Nera handset or via a Bluetooth handset. Thrane & Thrane Explorer™ 500 Over a standard IP connection, it connects at up to 464kbps in the receive direction and 448kbps when sending. Streaming data is available at speeds of 32kbps, 64kbps or 128kbps for both send and receive. The terminal connects to a laptop computer via USB, Bluetooth or Ethernet. Voice is delivered via a standard desktop phone or a Bluetooth handset. Addvalue (Wideye™) Sabre™ 1 Over a standard IP connection, it connects at up to 384kbps in the receive direction and 240kbps when sending. It also supports streaming IP services at 32kbps or 64kbps for both send and receive. Data connections are via USB or Bluetooth. Voice is delivered via a standard desktop phone or Bluetooth handset or headset. Service Features BGAN Network services include IP packet-switched data services (both background and streaming class; circuit-switched services, basic telephony (4kbit/s toll quality), 64Kbps ISDN data/Multimedia (64Kbps, H.324/m), short messaging (SMS) and supplementary services (i.e., call forwarding, voicemail), and a range of pre-paid service options. BGAN applications include e-mail, LAN access, high-speed file transfer, Internet access, intranet/extranet access, video-conferencing / video broadcast, and voice. The service will offer higher data rates than other mobile satellite services and terrestrial mobile data services, along with greater portability and flexibility than VSAT systems, with little or no set-up time or costs. A significantly greater coverage footprint than terrestrial mobile services and fixed infrastructure, and a greater reliability and ease of use than other mobile satellite data services will provide commercial and government users an entirely new communications platform, including secure access to corporate or home office VPNs. For pricing and additional information on BGAN service, contact AOS. Satellite Access Stations The I-4 spacecraft will link to Inmarsat's own Satellite Access Stations (SAS) - two sites located in Italy (Fucino) and the Netherlands (Burum) respectively, which then interconnect to the terrestrial networks. The system will employ bandwidth efficient modulation and coding techniques, capable of supporting variable bit-rate services and quality of service depending on the needs of the application. A range of terminals will be supported, ranging from small personal devices linking up with handheld and notebook PCs, aeronautical and maritime vehicular installations linking up with on-board entertainment and communications systems, to remote base stations linking up with local area networks.
