LightSquared has had a pretty rough year. After receiving conditional FCC approval to build a nationwide broadband internet service in early 2010, the same organization recently suspended development. Not too long after the approval was granted, concerns were brought to the FCC?s attention regarding potential GPS signal interference, as the powerful LTE broadband signals would be passing nearby, weaker GPS signals. LightSquared?s technology underwent a series of tests, which showed significant interference in nearby GPS receivers.

Following the results, LightSquared made its disappointment known. The company placed responsibility for the signal interference on weak GPS signal receivers, and even accused the FCC of rigging the testing process. The company was particularly concerned by the fact that the testing was done in private. The controversy caught the attention of the U.S. House of Representative?s Energy and Commerce Committee, who recently launched an investigation.

On February 28th, 2012, three nearly identical letters were sent to the heads of the FCC, the National Telecommunications and Information Administration (NTIA), and the co-chairs of the National Space-Based Positioning, Navigation, and Timing Executive Committee (PNT ExCom). The letters were sent by the Energy and Commerce Committee Chairman Fred Upton (R-MI), Communications and Technology Subcommittee Chairman? Greg Walden (R-OR), and Oversight and Investigations Subcommittee Chairman Cliff Stearns (R-FL). At the brunt of the investigation is the FCC?s decision making process, regarding the initial approval and testing process.

The letters are requesting copies of all written and electronic communication from April 2009 to present between all parties involved in the dispute, including LightSquared, the FCC, Harbinger Capital Partners (LightSquared?s primary investor), and GPS manufacturers. The committee will investigate suspicions that the FCC conducted little to no testing for GPS signal interference issues before granting LightSquared permission to develop their high-powered LTE network. The committee is also trying to find a way ?to ensure that GPS devices procured and used by federal agencies are appropriately constructed so that future deployment of terrestrial service in spectrum near or adjacent to the GPS bands will not impact GPS service.?
