CHARLESTON, SC (BusinessWire EON) July 27, 2007 --
ViaSat Inc. (Nasdaq:VSAT) demonstrated its DISA certified MD-1366
Enhanced Bandwidth Efficient Modem (EBEM) to members of the U.S. Navy
satellite team at the Space and Naval Warfare Center located in
Charleston, SC, showing how the modem dynamically adjusts its modulation
and coding for optimum performance and includes automatic antenna
handover to achieve industry leading data throughput. The combination of
ViaSat EBEM modems, an L-3 Communications NARDA Satellite Networks 3.9
meter Ground Multi-band Terminal (GMT), and the XTAR LLC high-powered
steerable-beam satellite makes the high level of performance possible.
Working with L-3 NSN and XTAR, ViaSat presented off-the-shelf
capabilities that can solve the U.S. Navy need for improved throughput
to surface ships. The newly DISA-certified U.S. Army and U.S. Navy
standard EBEM demonstrated individual terminal throughput rates ranging
from 50 Mbps to 155.52 Mbps. The demonstration also showed the value of
the advanced QPSK, 8-PSK, and 16-APSK modulations and Turbo codes
(MIL-STD-188-165B pending) that enable the EBEM (operating at 16-APSK
R=7/8) to achieve 205 Mbps total capacity on a single XTAR transponder,
the highest capacity ever achieved on a 72 MHz X-band transponder.
Two innovative functions are important keys to the new level of
performance achieved by the ViaSat EBEM.
Information Throughput Adaptation (ITA) increases available throughput
by converting power margin, typically reserved for overcoming adverse
weather conditions, directly to increasing data rates in normal
conditions to achieve vastly higher throughputs than available in
MIL-STD-165A and other COTS modems. ITA provides automatic, seamless
adjustments in modulation and coding to maximize performance even during
adverse weather conditions. The system data rate rises as downlink power
increases, and automatically falls back as downlink power decreases.
During the demonstration, the EBEM showed its seamless, error-free
adaptation to data rates from 28 to over 155 Mbps without operator
intervention. This powerful feature will be especially useful for the
Navy when the new Wideband Global SATCOM (WGS) satellites come on-line.
Automatic error-free antenna handover (AH) is critical to U.S. Navy
shipboard applications for maintaining communication synchronization
with the satellite during maneuvers as the ship terminal switches
antennas to maintain a constant view of the satellite.
The ViaSat MD-1366 EBEM modem is the new FDMA (Frequency Division
Multiple Access) standard and next state-of-the-art modem to support the
communications, command, and control requirements of today’s
highly mobile, joint U.S. forces using military and commercial
satellites at C-, X-, Ku- and Ka-band frequencies. In addition, the
MIL-STD-188-165 Working Group plans to incorporate the advanced features
and capabilities of the MD-1366 EBEM into MIL-STD-188-165B that will
supersede MIL-STD-188-165A.
The demonstration included the L-3 Communications NSN GMT System and 3.9
Meter transit-case antenna. Housed in a weatherproof transit case, the
3.9 meter Lightweight Medium Aperture Antenna (LMAA) is designed for
repeated worldwide tactical deployment. To learn more about L-3, please

The high powered XTAR steerable beam transponders allow all users,
including those with small and/or legacy terminals to receive and
transmit data at higher rates than previous X-band satellites. Visit www.xtarllc.com
