(Reuters) - LightSquared, the wireless startup backed by hedge fund manager Philip Falcone, on Monday filed for Chapter 11 protection.

The company and many affiliates filed for protection from creditors with the U.S. bankruptcy court in Manhattan. It has more than $1 billion of both assets and liabilities, according to the bankruptcy petition. The filing was expected.

LightSquared's future had been thrown into doubt in February when the U.S. Federal Communications Commission said it would revoke permission to build out a new high-speed wireless network.

The FCC made the decision because the planned network threatened to interfere with global positioning systems used by the military and various industries.
