Panasonic-Sponsored Paper Says 5.9 GHz Wi-Fi Would Short-Shrift V2X

The 5.9 GHz band should be reallocated for vehicle-to-everything communications, with no allocation for Wi-Fi, argued a Panasonic white paper filed at the FCC. The commission is expected to consider the band in November (see 2009090058). “Reallocating 45 megahertz of 5.9 GHz spectrum for unlicensed use" would require forgoing "the significant safety benefits associated with next-generation V2X applications,” said the paper, written by Wiley. “Sensor sharing messaging (aka cooperative perception messaging) would require at least an additional 20 megahertz,” it said: “Likewise, maneuver coordination messaging would require at least an additional 20 megahertz, and truck platooning 10 megahertz more. It is mathematically impossible to support these life-saving V2X applications, in addition to the Basic Safety Message, in only 30 megahertz of spectrum.” The paper was posted Wednesday in docket 19-138.
