If the FCC placed restrictions on how much power could be used on those bands and this company is violating those restrictions then they’re going to lose, and deservedly so.
But - if they are staying within the power restrictions they’ve got a case.
At this point we need to see spelled out what the FCC’s actual regulations were when they issued LightSquared their licenses for the frequencies they’re using, and we need to see spelled out what LightSquared’s actual plans are for those frequencies. If the FCC set up regulations on those frequencies taking into account the limitations of consumer-based GPS receivers and LightSquared is gaming those regulations then I’ll side with LS’s opponents.
They are not broadcasting yet. The rule is already in place. The studies have shown that if they do broadcast, they will interfere with existing GPS receivers.
The story is that they are using political connections to change the rules in their favor.
The rules are published, you can find them if you wish.
