LightSquared, Trimble Reach Agreement on GPS/LTE Interference

Trimble formally signed onto LightSquared's proposal that LightSquared will give up any terrestrial plans for 1545-1555 MHz as part of a means to ending objections to the proposed LightSquared L-band terrestrial broadband service. In a filing posted Thursday in docket 12-340, LightSquared said it and Trimble signed an agreement that mirrors similar agreements inked with Deere and Garmin last year that also had LightSquared ending its 2013 legal claims against them (see 1512180020). "It completes the picture," LightSquared counsel Gerard Waldron of Covington & Burling told us. "We can say we have final settlement agreements with the largest GPS companies, the end of litigation is upon us, these disputes have been solved." Unlike past agreements with Deere and Garmin, Waldron said, the Trimble agreement also has it and LightSquared telling the Transportation Department there's no need for the agency to test upper spectrum compatibility issues as part of the agency's pending GPS/LTE compatibility study, given the technical limits the satellite company has agreed to with the three GPS companies. Under the Trimble agreement, LightSquared said it will seek dismissal with prejudice of its suit against Trimble and the U.S. GPS Industry Council. LightSquared also agreed through January 2020 to keep records of base station activations involving use of 1627.5 MHz and higher and allow Trimble access to those records as a means of supporting resolution of any interference issues. The agreement also said Trimble, like Deere and Garmin, doesn't object to LightSquared's deployment of its terrestrial network under the technical specifications laid out in the agreements -- those specifications including foregoing terrestrial use of the 1545-1555 band. It also said it echoes LightSquared's call for the FCC to put out a public notice seeking comment on the GPS company agreements (see 1512310016). Trimble didn't comment. In a statement, LightSquared said the agreement "not only addresses pending policy issues related to new LightSquared's spectrum but also supports a regulatory path forward." LightSquared declined to comment on the status of its own commissioned study by Roberson and Associates of possible interference between its broadband uplink and downlink signals and neighboring spectrum GPS signals.
