Because Harris engineers continuously strive to improve all
aspects of Harris equipment, specifications are subject to
change without notice.
1.6 CONFIGURATIONS
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-VU104 Land Mobile BGAN Terminal
• RF-7800B-DU024 Land Portable BGAN Terminal
1.7 BGAN NETWORK
BGAN operates with the INMARSAT 4 satellite constellation of four 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 Alphasat satellite offers additional frequency ranges of 1668 - 1675 MHz and 1518 - 1559 for transmit and
receive, respectively. 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.
