Globalstar's TLPS Test Results Still Not Answering Bluetooth Questions, Gerst Capital Says
Globalstar's recent terrestrial low-power service (TLPS) test deployment results have gaping holes, as the company still hasn't made any data available on how TLPS effects Bluetooth and Bluetooth Low Energy devices, and the methodology used in that test deployment "raises…

a series of basic questions," Gerst Capital said in an FCC filing posted Wednesday in docket 13-213. Globalstar in its test results (see 1509110018) "dramatically overstates" the increased Wi-Fi capacity that comes with TLPS "by ignoring the ... 5GHz channels freely available today," Gerst said. Controlled testing of TLPS alongside Wi-Fi channel 11 shows interference, Gerst said, and previous Globalstar testing actually removed coexistence filters and also was not configured at maximum power -- which would have resulted in notably higher Bluetooth and Channel 11 interference. The FCC should either terminate the proceeding or -- if it still needs further analysis or test data -- put out updated guidance so interested parties can focus on providing that information, Gerst said. It said that Greg Gerst, principal at the hedge fund and a frequent TLPS plan critic (see 1503190025), met with legal advisors for commissioners Mignon Clyburn, Michael O'Rielly, Ajit Pai and Jessica Rosenworcel. Globalstar has dismissed Gerst criticisms in the past as coming from a shortseller trying to create doubt. In its own ex parte filing posted Tuesday, Globalstar said it met with those same legal advisors to go over those TLPS test results and urged the FCC to adopt the 2013 proposed rules that would allow TLPS deployment "without further delay." Another Globalstar TLPS critic, the Wireless Communications Association, has also said the TLPS deployment test didn't end interference worries and questions (see 1509210041).
