RESTON, Virginia, June 20, 2011 -

LightSquared™, the nation’s first wholesale-only integrated
wireless broadband and satellite network, today outlined a
comprehensive solution to the problem of interference with Global
Positioning System (GPS) receivers. This solution will permit
LightSquared to proceed with its business plan, protect the
public’s stake in GPS and lay the foundation for the future
co-existence of a variety of wireless broadband services and

“This is a solution which ensures that tens of millions of GPS
users won’t be affected by LightSquared’s launch. At the same time,
this plan offers a clear path for LightSquared to move forward with
the launch of a nationwide wireless network that will introduce
world class broadband service to rural and underserved areas which
still find themselves on the wrong side of the digital divide,”
said Sanjiv Ahuja, LightSquared Chairman and CEO.

Results of Testing

Early test results indicated that one of LightSquared’s 10MHz
blocks of frequencies poses interference to many GPS receivers.
This block happens to be the specific set of frequencies that
LightSquared planned to use for the initial launch of its
nationwide wireless broadband network.

Based on those same early test results, LightSquared determined
that another 10MHz block of the spectrum did not create such an
interference risk. This block is lower on the spectrum band and
located further away from the GPS frequencies, greatly reducing the
risk for interference.

Test results show this lower block of frequencies is largely
free of interference issues with the exception of a limited number
of high precision GPS receivers that are specifically designed to
rely on LightSquared’s spectrum. In its original plan, LightSquared
planned to move into this other frequency block as its business
grew over the next two to three years.

LightSquared’s Plan

After assessing this information, LightSquared immediately began
developing an alternative deployment plan focused on the lower
block of spectrum to launch its nationwide wireless broadband
service. It also entered negotiations with Inmarsat, the satellite
company that controls the alternative block of spectrum in the L
Band, to accelerate the schedule for LightSquared to begin using
the frequencies.

LightSquared recently reached an agreement with Inmarsat that
will allow the rollout of its wireless network in a timeframe that
keeps to the original business plan and is in accordance with
regulatory requirements. As part of this revised plan, LightSquared
will modify its FCC license to reduce the maximum authorized power
of its base-station transmitters by over 50%. This action will
limit LightSquared to the power it was authorized to use in 2005,
which will provide additional protection to GPS.

This new plan will give LightSquared enough spectrum to serve
its growing customer base for the next several years. During this
time, LightSquared will not use the spectrum it originally planned
to use for the launch of its network.

LightSquared will use this time to work closely with the FCC and
the NTIA, as well as the relevant US government agencies and
commercial GPS users, to explore mitigation possibilities and
operational alternatives that will allow LightSquared to continue
to expand its business and serve American consumers’ increasing
need for wireless broadband services which are so critical to the
development of a 21st century economy. At the same time,
LightSquared is committed to protecting GPS services, which have
become indispensible to millions of Americans.

LightSquared believes that its next-generation, 4G LTE wholesale
network can live harmoniously, side-by-side, with GPS users.
Enlightened and responsible spectrum management will give the
American public the best of both worlds - a world class wireless
broadband network and a GPS service that continues to enrich and
protect our lives. With this plan, LightSquared has taken a giant
step toward that goal.

About LightSquared

LightSquared’s mission is to revolutionize the U.S. wireless
industry. With the creation of the first-ever, wholesale-only
nationwide 4G-LTE network integrated with satellite coverage,
LightSquared offers people the speed, value, and reliability of
universal broadband connectivity, wherever they are in the United
. As a wholesale-only operator, LightSquared will deploy an
open 4G network to be used by existing and new service providers to
sell their own devices, applications, and services - at a
competitive cost and without retail competition from LightSquared.
The deployment and operation of LightSquared’s network represents
more than $14 billion of private investment over the next eight
years. For more information about LightSquared, please go to href="">
