LightSquared claimed impropriety last month in the tests performed by nine federal departments and agencies which summarized in a letter to the National Telecommunications and Information Administration (NTIA) there are "no practical solutions or mitigations that would permit the LigthSquared broadband service, as proposed, to operate in the next few months - or years - without significantly interfering with GPS."
Jeff Carlisle, Light Squared's executive vice president of regulatory affairs and public policy holds that because GPS devices are unlicensed, they should not be protected under FCC rules from interference from adjacent and nearby users.
According to Urgent Communications, it is unlikely that this filing will change any part of the decision-making process. GPS advocates claim that although the devices are not licensed, they are operating on authorized spectrum, and the real issue is LightSquared stepping beyond the normal use of satellite spectrum to terrestrial use.
