Abstract: This talk will present a number of candidate technologies for vehicle to vehicle and vehicle to infrastructure communications. In more detail it will describe 802.11p and LTE applied for vehicular applications. The effect of vehicle speed, packet size and antenna correlation will be described. Simulation and emulation results will be presented. Then we will consider the challenges and opportunities of mmWave for vehicular communications. The talk will also present current projects on vehicular communications such as the VENTURER project and a summary of current CSN group activities.
