Sirius XM “extremely disturbed” by FCC wireless non-interference proposals
Sirius XM satellite radio CEO Mel Karmazin warned the Federal Communications Commission on Thursday that the FCC’s proposed non-interference rules with a nearby wireless band won’t do.
“We are extremely disturbed by the proposal,” Karmazin confided in a letter sent to the agency’s Chair, Julius Genachowski. “The proposed rules seem to bear little resemblance to the technical record in this proceeding. More importantly, the proposal raises the real and direct threat of crippling interference to our 35 million current listeners and the 90 million satellite radio-equipped vehicles that will share the road with mobile WCS by 2015.”
As we’ve reported, Sirius XM and the owners of spectrum in the Wireless Communications Services band have been wrangling for years about how to avoid interference, given the nearness of their licenses to each other in the 2.3 GHz zone. The owners of WCS, which include AT&T, Comcast, and NextWave, want to step up use of the region for broadband, but these interference concerns have gotten in the way.
Last year, WCS reps proposed compromise limits on transmission power for WCS base stations and Sirius XM repeaters. But Sirius questions whether the interference tests conducted in Ashburn, Virginia upon which the recommendation was based would be as accurate as looking at Clearwire’s WiMAX network in the Philadelphia area, especially when it comes to mobile video use. “As this data was based on the real-world functioning of an operational WiMAX system, it provides a more transparent look into mobile handset performance than any other WiMAX-related information or description previously filed in these proceedings,” the company wrote last month.
WCS and Sirius XM engineers had a meeting about the FCC’s latest proposals on Tuesday. We don’t have a copy of the plan, but here’s the rest of Karmazin’s reaction to it: (more…)
