GPS group seeks partial ban on LightSquared

A group of GPS vendors and users has asked the U.S. Federal Communications Commission to permanently block LightSquared from using the upper band of its licensed radio spectrum for a cellular data network.LightSquared wants to build an LTE (Long-Term Evolution) network using frequencies near the band used by GPS. The FCC has said it can only do so if interference between the two systems is resolved. After tests showed strong interference in the upper 10MHz band of LightSquared’s frequencies, the carrier said it would start by operating on a lower band, which is also 10MHz wide. However, it holds out hope of using the upper band in the future.In a filing (PDF) to the FCC, the Coalition to Save Our GPS asked the agency to immediate.
