After an interesting battle with the FCC, LightSquared, and subsequently Sprint, who had announced a plan to partner with LightSquared for 4G LTE, the company has been dealt a crippling blow. The FCC has suspended a waiver granted to them in 2010, that would allow them to build-out their LTE network. The waiver was revoked over concerns that the spectrum used by LightSquared would be dangerously close to navigational GPS, and that it could affect up to 75% of GPS signals.
The National Telecommunications and Information Administration, in a letter,
Based on NTIA's independent evaluation of the testing and analysis performed over the last several months, we conclude that LightSquared's proposed mobile broadband network will impact GPS services and that there is no practical way to mitigate the potential interference at this time.
What does LightSquared have to say about all of this? Hit the break.
