ViaSat Delivers 2000th MD-1366 EBEM Modem and Receives Additional Orders from the U.S. Army : Newest DoD standard modem expected to become most widely deployed bandwidth efficient modem

Share Article

ViaSat Inc. (Nasdaq:VSAT) has delivered the 2000th Enhanced Bandwidth Efficient Modem for U.S. Department of Defense teleport and U.S. Navy operations. The MD-1366 EBEM is interoperable with all legacy U.S. DoD modems, implements Mil-Std-188-165A, and includes new, efficient modes (Mil-Std-188-165B) for high-speed, point-to-point, satellite communications at fixed, quick-deploy, airborne, and shipboard installations. ViaSat also received additional follow on orders for another 100 EBEMs from the U.S. Army Communications and Electronics Command (CECOM) headquarters. Users cite increased throughput capacity, enabled by the ability to put more carriers on a single satellite transponder, as the primary advantage of the MD-1366 over other military point-to-point satcom modems.

The EBEM includes a number of improvements over Mil-Std-188-165A modems:

More bandwidth capacity through a new set of open standard features Lowered system cost and weight with integrated Federal Information Processing Standards (FIPS) 140-2 security, protecting all control, monitoring, and user traffic Certification for the new Wideband Global Satcom system Operation on commercial or military satellites in the X-, C-, Ku-, and Ka-band Compatible with legacy military standard hardware "Software defined MD-1366 modems can interoperate with deployed U.S. DoD and intelligence terminals and provide a cost-effective performance upgrade path that can either reduce satellite costs or increase throughput," said Ric VanderMeulen, VP and general manager of Government Satcom at ViaSat. "We were selected by the U.S. Army as the price and performance leader and we anticipate that EBEM will become the most widely deployed point-to-point modem in the U.S. DoD inventory."

The EBEM features advanced modulation and code rate options to optimize bandwidth efficiency, tighter carrier spacing to increase bandwidth capacity, improved signal-to-noise performance for power efficiency, and rates up to 155 Mbps compared to 20 Mbps rate for the modems it replaces. AUPC (Automatic Uplink Power Control), which keeps the link connected and maintains a constant throughput rate in harsh environments, ensures high performance regardless of heavy weather and other variations in satellite signal strength.
