For Falcone's LightSquared venture, the GPS interference issue is looking less like a speed bump and more like a brick wall. After asking for more time, the company this week said it could perhaps make a few modifications to its plan that would interfere with fewer devices by cutting power and starting with a different frequency range than initially planned, an idea that seems to have pleased precisely no one. Especially not the House of Representatives, where the House Appropriations Committee has now adopted an amendment prohibiting the FCC from issuing the company a permit if they can't prove they have a solution. While there remains the option of using other spectrum, that would seem to make whole swaths of the original rationale for this project pointless. What do you think, is there anything left here for Falcone and LightSquared?
