The Intelligent Transportation Society of America and two major automaker lobbying groups were among the entities co-signing in a letter to the U.S. Federal Trade Commission urging it to protect the 5.9-GHz radio band for use with connected-vehicle technologies including vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) systems. The FCC had allocated the band exclusively for that purpose, but is now entertaining the idea of opening it to unlicensed Wi-Fi-based devices also. The commission is scheduled to discuss a proposal to that effect at its Feb. 20 meeting. The letter by ITS America, the Alliance of Automobile Manufacturers, the Association of Global Automakers, and others asks that action by the FCC in this regard be held off until the U.S.'s NHTSA (National Highway Traffic Safety Administration) completes its study of V2V and V2I technologies using the 5.9-GHz band. The auto safety agency is putting those technologies to test in what it calls the largest-ever on-road demonstration project and, depending on the test results, might call for permanent reservation of the 5.9-GHz band. That project began last year on roads and highways in the Ann Arbor, MI, area and involves about 3000 specially equipped cars, trucks, and buses operated by volunteer participants.
