LightSqaured may interefer with 75% of GPS devicesAccording to a draft report, LightSquared wireless service interferes with 69 out of 92 devices that have been tested, or 75%. We have reported earlier that LightSquared and the FCC have come under fire by Senator Charles Grassley (R-IOWA) because the FCC had approved testing without review by the Senate Judiciary Committee. Grassley has committed to blocking any nominations to replace two of the missing FCC board members until the FCC shares internal documents related to the decision to allow LightSquared to move forward.

The tests were conducted by the National Space-Based Positioning, Navigation and Timing Systems Engineering Forum that advises policy makers and included the Department of Defense and the Federal Aviation Administration in the testing.

LightSquared is a startup funded by Falcone’s Harbinger Capital Partners is using spectrum that is close to GPS spectrum to create a satellite based broadband cell network that would provide broadband wireless to 260 million people and could be part of a solution to reducing the last mile and access inequality issues that currently exist with broadband access in the U.S.

LightSquared says the preliminary test results should not have been leaked, and that the tests were overly conservative, defining the term "harmful interference" in a way that renders the term meaningless.
