LightSquared has filed for bankruptcy protection, saying that will give it more time to win regulatory approval. Regulators have blocked LightSquared's plans, saying they could interfere with GPS signals.
Wireless Internet connections from LightSquared can confuse GPS devices. Now, the FCC says it may revoke LightSquared's permit to eliminate the risk of such interference.
LightSquared will launch a new wireless broadband network that aims to provide competition to the incumbent phone companies.
