The Inmarsat BGAN system
What is BGAN?
The Broadband Global Area Network (BGAN) is a mobile satellite service that offers high-speed
data up to 492 kbps and voice telephony. BGAN enables users to access e-mail, corporate
networks and the Internet, transfer files and make telephone calls.
Coverage
The Inmarsat BGAN services are based on geostationary satellites situated above the equator.
Each satellite covers a certain area (footprint). The coverage map below shows the footprints of the
BGAN system.
Note The map depicts Inmarsat's expectations of coverage, but does not represent a guarantee
of service. The availability of service at the edge of coverage areas fluctuates depending
on various conditions.
The launch of the F3 satellite (POR) is planned for 2008.
Note Certain BGAN services may not be available in areas with low elevation.
(Launch planned
for 2008)

The BGAN services
Supported services
The services currently supported by BGAN comprise:
• A Packet Switched connection to the Internet
• A Circuit Switched (Dialed) connection for voice, fax or data
• Short Messaging Service (SMS)
Packet data service
The BGAN network supports different classes of data connection to the Internet.
• Using a Standard data connection several users can share the data connection
simultaneously. This type of connection is ideal for e-mail, file transfer, and Internet and
intranet access. The user pays for the amount of data sent and received.
• Using a Streaming data connection you get an exclusive high-priority connection ensuring
seamless transfer of data. This type of connection is ideal for time critical applications like live
video over IP. The user pays for the duration of the connection (per minute charge).
Circuit switched (dialed) service
The following types of circuit switched connection are available:
•Standard Voice. A low-tariff connection for voice only. The voice signal is compressed to
4.0 kbps, which reduces the bandwidth use and consequently the tariff.
•3.1 kHz Audio. A high quality connection which can be used for Premium Voice, G3 fax or
analog modems. The signal is uncompressed 3.1 kHz audio, which allows for optimum voice
quality.
•ISDN. A high quality connection which can be used for voice (3.1 kHz Audio), G4 fax or 64 kbps
UDI/RDI data.
SMS service
The BGAN system provides a Short Messaging Service (SMS) for sending and receiving SMS
messages.
Note The BGAN system supports maximum 11 concurrent PS connections at a time per
EXPLORER 727 system.
Note The BGAN system only supports one external CS call at a time per EXPLORER 727 system.
