LightSquared Executive Vice President for Regulatory Affairs and Public Policy Jeff Carlisle said the U.S. government’s testing had already confirmed that more than 300 million GPS-enabled cell phones were compatible with LightSquared’s signal.

   “As we anticipated, the data shows that properly filtered high-precision GPS devices do not suffer any loss of accuracy in the presence of LightSquared’s signals. The government has not yet begun the next phase of testing, which will focus on high-precision devices, so this is an important indicator as those tests get underway,” Carlisle said in a statement.

   LightSquared plans to invest $14 billion in private equity in U.S. broadband infrastructure. The company said it would continue to work with the U.S. government to arrive at a complete solution so that it may begin building out its network.
