Congressman Mike Turner has toughened up language in the bill intended to ensure that potential FCC approval of a commercial network like LightSquared doesn't harm the military’s use of GPS. The revisions state that the FCC shall not provide authorization for the LightSquared terrestrial LTE service until Defense Department's concerns about GPS interference have been resolved.
Why this matters DoD concerns about LightSquared could potentially lead to further delay and testing and possibly finally sink the network plans. A joint statement by the departments of transportation and defense late Wednesday said that Air Force tests found that the network could cause "harmful interference to the majority of other tested general purpose GPS receivers."
For its part, LightSquared claimed this week that it has already addressed concerns about all but a few handheld GPS receivers and that the tests assumed a much higher transmit power than the network will actually use. The company expects to start a round of testing of high-precision receivers in January.
Nonetheless, the company now appears to have ever-increasing odds stacked against the network ever getting off the ground.
