From Bloomberg:

LightSquared Inc. filed for bankruptcy, saying it will seek to resolve the concerns of U.S. regulators who thwarted the company’s plan to deliver high-speed wireless to as many as 260 million people.

LightSquared, based in Reston, Virginia, listed assets of $4.48 billion and debt of $2.29 billion as of Feb. 29 in a Chapter 11 filing yesterday in U.S. Bankruptcy Court in Manhattan. The filing followed intense negotiations with creditors, who had requested that the company’s backer, Philip Falcone, step aside. Falcone and the current management team will remain with the company, Terry Neal, a LightSquared spokesman, said yesterday.

Falcone’s plan for LightSquared depended on winning FCC approval to convert airwaves originally designated for satellite service to spectrum for land-based radio towers. LightSquared invested $4 billion in airwaves and reached deals with more than 30 partners, including Best Buy Co. (BBY).

LightSquared hit a roadblock in February when the FCC said it would withdraw preliminary approval for the company’s network after government tests found that the signals would interfere with global-positioning systems.
