LightSquared on Tuesday issued a letter to the Federal Communications Commission ostensibly demanding approval to build out its 4G LTE network. LightSquared executive vice president of regulatory affairs and public policy Jeff Carlisle argued that the GPS industry has had almost 10 years to address issues that cause GPS satellite signals to partially transmit on spectrum that LightSquared has licensed. The letter was written in response to an announcement earlier this week from federal officials, stating that they were still concerned about interference LightSquared’s network causes with GPS equipment after conducting a new investigation into the matter. “LightSquared has had FCC authorization to build its network for over eight years and that authorization was endorsed by the GPS industry, and fully reviewed and allowed to proceed by several other government agencies,” Carlisle wrote in the letter. “Commercial GPS device-makers have had nearly a decade to design and sell devices that do not infringe on LightSquared’s licensed spectrum. They have no right to complain in the eleventh-hour about incompatibility when they had ample opportunity to avoid this problem.” A link to LightSquared’s full letter follows below.
