Vehicle-to-Vehicle (V2V) technology allows connected vehicles to wirelessly communicate with each other to warn drivers of potential dangers. With this information, the driver can take action to reduce the severity of the collision or avoid it completely. The National Highway Traffic Safety Administration (NHTSA) says that this technology could be a "game changer," potentially addressing 80% of vehicle crashes involving non-impaired drivers.
Several major automakers and numerous technology providers have been working with NHTSA researching the potential safety benefits of V2V. These systems rely on wireless technology in the 5.9 GHz frequency band.
Currently, the Federal Communications Commission (FCC) is exploring whether this spectrum can be shared with unlicensed Wi-Fi devices, a decision that automakers believe should not take place until it can be proven there will be no interference.
