Concerns Raised on Different Aspects of 5.9 GHz Rules

The FCC is getting oppositions (see 2011030053) on draft rules, set for a commissioner vote next week, allowing Wi-Fi to share 45 MHz of the 5.9 GHz band. Filings were posted Monday in docket 19-138. Facebook opposes exclusion zones there. The proposal relies on “profoundly flawed analysis of federal radar operations authorized in the 5.9 GHz band -- an analysis whose assumptions about Wi-Fi operation are both inaccurate and inconsistent with the Commission’s own assumptions in the 6 GHz Order,” Facebook said: “Because the NTIA analysis did not appear in the record until very recently (Oct. 23rd), the parties have not yet had a meaningful opportunity to study and respond.” The order would “cement in place” cellular vehicle-to-everything “as the presumptive technology standard for all future automotive communications technologies,” Continental Automotive Systems said. “Because in many cases licenses to the technology at the core of C-V2X cellular standards are not directly available to many automotive industry participants in the supply chain, or if so are often subject to unreasonable terms, the exclusive use proposal generates the potential for patent holders to abuse and distort the market for the next-generation of automotive communications,” Continental said: “The Commission should have a full understanding of the consequences to the automotive supply chain in this regard.” The company spoke with Office of Engineering and Technology and Office of Economics and Analytics staff.
