LightSquared
- January 26, 2011, the Federal Communications Commission (FCC) issued an Order and Authorization giving LightSquared conditional approval to build a ground-based wireless network using its authorized mobile satellite service (MSS) spectrum adjacent to the GPS L1 frequency band. The FCC required that LightSquared form a working group with the GPS community to address GPS interference concerns to the satisfaction of the FCC before commencing operations.
- June 30, 2011, LightSquared submitted its Technical Working Group (TWG) Report and a Recommendation Paper to the FCC.
- July 6, 2011 the NTIA submitted the National Space-Based PNT Engineering Forum (NPEF) Report to the FCC which recommends that the FCC continue to withhold authorization for LightSquared to commence operation.
- December 14, 2011, the National Executive Committee for Space-Based Positioning, Navigation, and Timing issued a press release summarizing the November 2011 test results of LightSquared's proposal to provide a new broadband service. Preliminary analysis of the test findings found no significant interference with cellular phones. However, the testing did show that LightSquared signals caused harmful interference to the majority of other tested general purpose GPS receivers.
