USER GUIDE

Inmarsat BGAN system

The Inmarsat Broadband Area Network service (BGAN)
provides both voice and broadband data through a
truly portable device on a global basis.
Data and voice transmissions to and from mobile/
fixed subscribers is offered anywhere within the
worldwide coverage of the Inmarsat 4 spot beam
system, see map later in the User Guide.
The benefit of the INMARSAT system is its high capac-
ity, and the rapid and reliable connec-
tion between the land based (fixed)
users and the Mobile Earth Stations
(MESs).
Each satellite region is under the
control of a Satellite Access Station
(SAS), which controls and monitors
the traffic between the MESs and
the SAS.
SAS: Satellite Access Station w/Dis-
tribution Partners (interconnects
fixed telecommunication networks
with the Inmarsat system, two in each
Ocean Region).
MES: Mobile Earth Station
(Nera WorldPro, a user terminal for the Inmar-
sat system).
