LIGHT SQUARED VS GPS: GOVERNMENT REPORT SAYS THERES NO WAY
FOR THE TWO TO CO-EXIST
More problems for LightSquared in its bid to construct a 4 G
network in spectrum adjacent to that used by the GPS
navigation system. Amateur Radio Newsline's Bruce Tennant,
K6PZW, reports:
--
A joint panel of representatives from nine federal agencies
says that it has determined that there are no practical
solutions that would allow LightSquared's proposed broadband
service to operate without significantly interfering with
the Global Positioning System or GPS that operates in
adjacent spectrum.
The report was made in a January 13th letter from the
National Executive Committee for Space-Based Positioning,
Navigation, and Timing to the National Telecommunications
and Information Administration. It said that over the past
year it has closely worked with LightSquared to evaluate its
original deployment plan, and subsequent modifications, to
address interference concerns. It said that substantial
federal resources were expended and diverted from other
programs in testing and analyzing LightSquared's proposals.
The report added that no further tests are warranted, as
LightSquared has not demonstrated any means that would
prevent such interference from occurring.
As previously reported, numerous tests over the past year
have shown that signals from LightSquared's proposed 4G
network held the potential to interfere with the weaker
signals from space used by global positioning system
receivers. As a result, In December 2011, the company
offered to limit its signal to lower frequency spectrum
farthest away from the bandwidth used by GPS in exchange for
immediate access to that spectrum. Then as reported last
week LightSquared lashed out at the GPS industry in a
Federal Communications Commission filing, claiming poor
design of GPS units is solely to blame for the problem.
Not surprisingly, LightSquared immediately issued its own
press release calling for the FCC and NTIA to retake the
lead on conducting tests of its network, claiming the
committee report demonstrated bias and inappropriate
collusion with the private sector. LightSquared noted a
director for Trimble GPS, whom is called an outspoken
LightSquared opponent, served as Director of the Advisory
Board. It also claims that government testing has become
unfair and shrouded from the public eye.

With the committee decision now on the books, a final ruling
from the FCC on whether LightSquared will be allowed to go
ahead with its plans to turn on its 4 G could come at any
time. (Various News Reports)
