Out with the old, in with the new, according to several cellular industry groups commenting on the U.S. National Highway Traffic Safety Administration (NHTSA) plan to use dedicated short-range communications (DSRC) to improve road safety.
The deadline was April 13 for the public to comment on the NHTSA’s plan, which proposes requiring vehicle-to-vehicle devices to “speak the same language” through standardized messaging and would require automakers to include V2V technologies in all new light-duty vehicles. Designating a single language would solve the problem of dueling protocols, but opponents argue that DSRC is already outdated and shouldn’t be mandated. In fact, many commenters don’t want to see any specific technology mandated at all.
The 5GAA, whose founding members include Ericsson, Intel, Huawei, Nokia, Qualcomm, Audi, BMW Group and Daimler AG, prefers Cellular Vehicle-to-Everything (Cellular-V2X) for V2V safety, saying it exceeds the capabilities of DSRC on more than one front. But 5GAA doesn’t want to see any technology mandated.
Next Generation Mobile Networks (NGMN), whose U.S. board members include AT&T, Sprint, T-Mobile, US Cellular, Verizon and Ligado Networks, commented in much the same vein, saying its V2X Task Force recommends the U.S. Department of Transportation (DoT) be technology neutral in the rulemaking.
