Startup satellite-terrestrial mobile broadband provider LightSquared urged the U.S. Federal Communications Commission (FCC) to rule against critics of the company who say its planned wireless Internet network would interfere with GPS systems, The Wall Street Journal reported Dec. 21.

Reston, Va.-based LightSquared asked the FCC to declare that the company has no obligation to pay for fixing the GPS interference issue and to stop its opponents from blocking the wireless network.

LightSquared partner Sprint Nextel Corp. has given the company until Dec. 31 to receive FCC clearance for the network as a condition of a 15-year spectrum- and equipment-sharing accord that LightSquared says will help it save $13 billion through the end of this decade.
