There have been a few anecdotal concerns raised over the last several weeks that LightSquared's proposed LTE network -- which would repurpose L-band spectrum formerly used for satellite -- is too close to the spectrum used by the Global Positioning System, leading to unintentional jamming when the towers overpower the much weaker GPS signals.
