LightSquared Proposes Vacating Disputed Spectrum

LightSquared proposed giving up its plan to use spectrum next to that used by global positioning systems if federal regulators will let it develop the rest of its planned nationwide broadband network. LightSquared unveiled a plan that calls for entirely vacating the "upper" 10 Mghz of spectrum closest to GPS signals, and delaying development of a "lower" 10 Mghz chunk of spectrum until the FCC enacts rules to prevent interference. Instead of using the upper spectrum, the company proposes pairing some of its existing spectrum with spectrum it could share with government users.
