IAI-2 Inmarsat Air Interface-2. The air interface used for BGAN. IAI-2 is an evolution of MPDS

with new bearer types, which give a wide range of data rates from 16 kbps up to 492 kbps.

By utilizing different modulation schemes, variable coding rate and power adjustment, it

is possible to change the bearer type to give optimum throughput with efficient use of the

satellite resources.

IMEI International Mobile Equipment Identity. A unique number identifying your terminal.

IMSO International Maritime Satellite Organisation. An intergovernmental body established to

ensure that Inmarsat continues to meet its public service obligations, including

obligations relating to the GMDSS.

office, school or airport. The defining characteristics of LANs, in contrast to wide-area

networks (WANs), include their usually higher data-transfer rates, smaller geographic area,

and lack of a need for leased telecommunication lines.

LED Light Emitting Diode

NAT Network Address Translation. An Internet standard that enables a local-area network to

use one set of IP addresses for internal traffic and a second set of addresses for external

traffic. A NAT module makes all necessary address translations.

PoE Power over Ethernet. A standard for combining power supply with transmission of data

over the Ethernet. The source unit "injects" power into the Ethernet cable and the power

is "picked up" at the connected device.
