An FCC proposal to suspend LightSquared’s ancillary terrestrial component authority...

and it is “entirely unsupported by the law, science and FCC policy and precedent,” Executive Vice President Jeff Carlisle told reporters. The FCC “need not and should not embrace the false choice presented by the GPS industry between preserving LightSquared’s ancillary terrestrial component authority to deploy a wireless broadband network and maintaining GPS service,” the filing said. The company invested $4 billion in its network, Carlisle told reporters: By calling for the revocation of the company’s ATC authorization, the GPS industry “wants the network to be demolished.” Carlisle said it’s important for ATC authority to be retained: Revoking it “makes it impossible for us to do business and it would be a reversal of 10 years of work that the FCC and our company put into this business plan.” The issue at hand is the inability of a limited number of GPS receivers “to operate properly in spectrum that has not been allocated for GPS use, and instead has been licensed to LightSquared for different purposes,” the filing said. LightSquared suggested ways to address this, including the FCC and NTIA working to develop spectrum solutions “to enable LightSquared to deploy its broadband wireless services in alternative spectrum.” The Coalition to Save Our GPS plans to file a reply urging LightSquared’s authorization to be revoked. LightSquared’s arguments are “requests for changes in the rules after the game is over, or requests for special treatment to avoid the consequences of its ill-conceived plans,” the coalition said in a news release. It said evidence demonstrates LightSquared hasn’t satisfied the condition “requiring that it demonstrate that it will not cause harmful interference to GPS receivers.” Testing conclusively shows “that LightSquared’s proposed terrestrial operations will cause harmful interference to GPS and that migration is not possible at this time,” the coalition said. The company is incorrect to describe ATC as an allocated service of mobile satellite service, the U.S. GPS Industry Council said in its reply: “ATC is authorized only as a component of the MSS allocation” under strict rules prescribed by the commission. Because LightSquared’s proposal would de-couple terrestrial use from the primarily allocated MSS service, it’s not ATC, “but a standalone ubiquitous, terrestrial mobile broadband offering,” the council said. Deployment of such a service would eviscerate the MSS allocation in the 1525-1559 MHz band and “replace it with operations of a wholly different character for which there is no spectrum allocation, and which are fundamentally incompatible with both co-frequency and adjacent frequency primary services,” USGIC said.
