Safety Improvement in Millimeter Wave Vehicle-to-Infrastructure Communications

Message transition with the lowest possible delay, is a critical need for safety applications of vehicle communications. But how we can reduce such delays In this paper, we investigate the use of millimeter waves (mm-waves) due to their wide bandwidth and higher data rates, compared to dedicated short range communication (DSRC) technology for vehicle-to-infrastructure (V2I) communications. We use a 3D ray tracing technique over two different actual environments: a high dense urban, and a low dense sub-urban area. Simulation results reveal that mm-waves have lower delay spread compared to the current DSRC technology.
