WARNING: This device emits radio frequency (RF) energy when in transmit mode. In order to
comply with FCC RF Exposure limits, the unit must be installed in such a way as to ensure that a
minimum separation distance of 18.5 inches (47cm) is maintained between the antenna and
any nearby persons.

3 TERMINAL OVERVIEW AND OPERATIONAL CONCEPT
The ViaSat AT2220 Terminal enables reliable and instant IP-based communications via
satellite for rotor and fixed-wing aircraft.
Powered by ViaSat L-band Managed Service (VMS), this satcom terminal’s two-way
networking capability enables both real-time monitoring of position location information
using built in GPS receiver, and data and voice communications. FIPS-certified data link
layer encryption is employed to ensure the integrity of user data is protected. The
terminal features easy-to-use interfaces and provides flexibility to configure to nearly any
sensor system or IP data application. Examples of operational scenarios that the AT2220
Terminal supports range from fleet management, emergency first responders, homeland
security forces, disaster aid workers, corresponders, mobile workforce management and
tracking of high-valued assets. This is all within an integrated single assembly package
that is optimized for airborne data transmission. A single cable provides DC power and
Ethernet for wired connections to an IP device, eliminating the need of RF cable typically
required for connection between modem and antenna. The transceiver also supports Wi-
Fi and Bluetooth for wireless connections to multiple tablets or smartphones. The
AT2220 Terminal is powered by ViaSat advanced waveform that allows for a low
latency and highest capacity of users to operate on a single L-band channel. A rendering
of the AT2220 Terminal is shown in the Figure 1. Terminal size, weight and
characteristics are provided in Section Error! Reference source not found..

ViaSat Proprietary PR000190 Rev. 004
The AT2220 terminal is designed to be flexibile in application, incorporating features and
functions that are important in M2M mobile applications. In particular, the terminal is
tailored to provide the followings:
Ruggedized design to handle harsh environments
Integral antenna & modem in a single low profile unit
Ethernet, Wi-Fi, Bluethooth interface options
Two-way send/receive connectivity
Low latency for instant message transfer and real time monitoring
Push To Talk (PTT) voice
Low service cost with a bandwidth efficient waveform
Optional dual receiver capability (can receive two forward links simultaneously)
Figure 2 illustrates the concept of operation. End-users operating on mobile or fixed
platforms access satellite service through the AT2220 terminals and assigned satellite
channel. A ViaSat hub accesses a satellite provider’s RF feeder link to provide satellite
service to the end-users and connectivity to the AT2220 transceivers in a hub-spoke
topology. A terrestrial VPN link connects the ViaSat Network Operation Center (NOC)
to the hub for network management and control through a commercial router.
