This study evaluates the performance of radio links and networks to support communication with Automatic Vehicle Control Systems (AVCS). It addresses both vehicle-to-vehicle communication and roadside-to-vehicle communication. The report contributes to the modelling of short range vehicle-to-vehicle channels, not only in terms of documenting measured results and channel parameters, but also in extending existing models to cover antenna mobility at both receiver and transmitter simultaneously. These models are applied to compute the Bit Error Rate performance over radio links. The network aspects considered here are queuing of packets in base station buffers, handovers, and interference from other transmitters in the system.
