In a letter to the Federal Communications Commission (FCC) on Sept. 28, bankrupt LightSquared Inc. asked U.S. regulators to let it share airwaves with federal government users – namely weather balloons and weather satellites. In return, the company would give up the right to some operations in airwaves near those used by GPS.
The FCC blocked the service in February after GPS device makers and users – including the U.S. military and commercial airlines – said that signals from LightSquared’s service would confound navigation gear. In a March filing at the FCC, makers and users of GPS equipment said there were “no feasible mitigation measures” to prevent interference from LightSquared.
The National Oceanic and Atmospheric Administration (NOAA) is the dominant user of the frequencies requested in the Sept. 28 proposal.
U.S. officials who manage frequency assignments are increasingly considering sharing-arrangements, as airwaves become crowded with new uses.
