Rosenworcel Seeks Vote on 5.9 GHz Rules
FCC Chairwoman Jessica Rosenworcel circulated for a commissioner vote a long-awaited order (see 2404180050) finalizing rules for cellular vehicle-to-everything use of the 5.9 GHz band, the agency said Wednesday. The order wasn’t circulated in anticipation of a vote during the…

commissioners' Aug. 7 open meeting. Accordingly, the FCC did not release the order's text. The order codifies “C-V2X technical parameters in the Commission’s rules, including power and emission limits and message prioritization,” a news release said. The rules provide flexibility for the auto industry “to use three 10-megahertz channels either separately, in combination as a 20 megahertz channel or as a single … channel” and would “establish prioritization of safety-of-life communications,” the release said. Licensees operating under C-V2X waivers wouldn’t need to change already deployed systems. The order also provides a two-year timeline for sunsetting existing dedicated short range communications technology, the FCC said. Under the rules, geofencing could be used to allow higher equivalent isotopically radiated power limits for on-board C-V2X units, as NTIA proposed. The proposal received broad support in comments just filed at the FCC (see 2407080024). “The evolution of the 5.9 GHz band advances new car safety technologies in an efficient and effective way while also growing our wireless economy,” Rosenworcel said: “This is sound spectrum management at work.” The order was circulated Tuesday, the FCC said. Rules for the band were changed late in 2020, allocating 45 MHz for Wi-Fi and 30 MHz for C-V2X technology (see 2011180043). “This is a very positive development -- and something we’ve been urging the FCC to greenlight for nearly four years,” emailed Hilary Cain, senior vice president-policy at the Alliance for Automotive Innovation. “C-V2X is an exciting safety technology and a perfect example of the sort of spectrum-enabled innovation that’s possible when the FCC and [the] auto industry work together,” she said.
