Millimeter-wave technology promises to revolutionize vehicle-to-vehicle communication. Unlike other systems, mmWave has a broad spectrum with high bandwidth, enabling vehicles to continuously share information as the precise location, speed and sensor data freely. This means that cars can perceive their environment better in that they become aware of their surroundings. mmWave V2V communication enables the exchange of information in real-time, and this is crucial in promoting cooperative perception which ensures improved road safety as it quickens how cars recognize or react to possible dangers. However, additional studies in mmWave technology are necessary to effectively address the problem of interference and signal reliability in high-speed traffic conditions. Moreover, the creation of inexpensive mmWave transceivers and signal processing algorithms is needed to make it viable for every-day vehicles. As these challenges are tackled, mmWave V2V communication can bring about the next revolution in the field of transportation, which allows for the development of a fully connected and intelligent transportation infrastructure.
