LightSquared Files Spectrum Plan with FCC

LightSquared submitted a new proposal to the FCC to address GPS interference issues with its planned hybrid LTE + broadband satellite network. The company claims this new plan resolves interference issues for 99.5 percent commercial GPS devices by moving the rollout of the network to a different spectrum block. Approximately 200,000 high-precision GPS units in the field would still suffer interference, but LightSquared said it is committed to resolving this issue as well.

LightSquared asserts the interference is caused "by the GPS device manufacturer's decision over the last eight years to design products that depend on using spectrum assigned to other FCC licensees." It believes that inexpensive filters could have been included in GPS device designs, and this would have prevented the problem.
