USA: According to a recent news, the Alliance of Automobile Manufacturers and The Association of Global Automakers submitted joint comments in response to an FCC proposal to allow unlicensed wireless devices to operate in the 5.9 GHz frequency band that has been designated for exclusive use for “time-critical” Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications.
As in news, automakers said that allowing unlicensed Wi-Fi devices to share spectrum with connected vehicles must not be permitted without thorough testing.
As per the source, Automakers are concerned that opening up the 5.9 GHz frequency band to other wireless uses could cause harmful interference and affect the integrity of these safety critical communications among cars, trucks, other road users and road equipment such as traffic lights. Communications delays of even thousandths of a single second matter when dealing with auto and highway safety.
Automakers, government agencies and others have already spent hundreds of millions of dollars in the research, development and testing of connected vehicle technologies. Currently, ten major automakers and numerous technology providers have been working with the Department of Transportation’s (DOT) Connected Vehicle Research Program in a pilot study of V2V performance. Nearly 3,000 cars, trucks, and transit buses are testing V2V and V2I technologies. The data from the pilot study will be used by the DOT for future potential regulatory decisions regarding communications systems for crash avoidance.
