The Federal Communications Commission said it will seek public comment as early as Wednesday, Feb. 15, 2012, on revoking LightSquared's permit after a federal agency that coordinates wireless signals, the National Telecommunications and Information Administration, concluded that there's no way to mitigate potential interference.
