For the equipment firmware revision used when documenting this manual, refer to the title page inside the front

cover of this manual. The BGAN terminals covered in this manual can be differentiated as follows:

 RF-7800B-DU024 Land Portable BGAN Terminal

1.7 BGAN NETWORK

BGAN operates with the INMARSAT 4 satellite constellation of three orbital satellites. See Figure 1-3. The map

shows the global coverage provided by the BGAN satellites. This BGAN system operates in the L-Band spectrum,

with a transmit frequency range of 1626.5 MHz - 1660.5 MHz, and a receive frequency range of 1525-1559 MHz.

The INMARSAT 4 constellation provides access worldwide.

Access a BGAN satellite by pointing the BGAN terminal to that satellite. In addition to the satellites, the BGAN

system includes infrastructure equipment on the ground, that connects to telephone networks and the internet. By

accessing the satellites, the BGAN terminal can then connect to telephone and data networks. To make use of BGAN

services, users must insert their GSM/GPRS/UMTS subscriber identity module into the BGAN terminal hardware,

and connect an external telephone handset and/or computer / Personal Data Assistant (PDA) to the BGAN terminal

via a cabled connection.
