The confrontation between LightSquared and the U.S. government and industry GPS interests is heating up. LightSquared was able to obtain an FCC waiver of its satellite broadcast license to build a supplemental terrestrial transmitter network for broadband wireless. The GPS community claims that LightSquared’s plan, using a radio frequency close to that of GPS, will create interference. On Friday, Rep.
