RESTON, Virginia, November 15, 2010 - LightSquared(TM), the nation's first wholesale-only integrated wireless
broadband and satellite network, today announced the successful launch of its
SkyTerra 1 satellite. Launched by International Launch Services (ILS), the

The satellite, a Boeing 702HP built by Boeing Space and Intelligence
Systems, is designed to provide wireless mobile services to millions of
subscribers. LightSquared's SkyTerra 1 satellite features a 22-meter L-band
reflector-based antenna — the largest commercial antenna reflector to be put
into service. The satellite, among the most powerful commercial satellites
ever built, will provide ubiquitous nationwide coverage and enable integrated
satellite-terrestrial service using products that are similar to today's
typical mobile devices in terms of size, capabilities and build costs.

"Today, LightSquared has achieved a major milestone in the realization of
our mission to revolutionize the wireless industry in the United States,"
said Sanjiv Ahuja, chairman and chief executive officer for LightSquared.
"LightSquared is launching the world's first truly integrated
satellite-terrestrial network, combining our 4G-LTE terrestrial network with
ubiquitous satellite coverage that will connect rural America and support
emergency communications."

"We thank the skilled engineering and operations teams of ILS,
Khrunichev, Boeing and LightSquared for their dedication and hard work that
made this a successful mission," Ahuja added.
