Experiments on vehicle to roadside microwave communication

Experiments on microwave communication between vehicle and roadside for road pricing (setting tolls) are described. Attenuation results from laboratory, static, and dynamic experiments are presented. It was concluded that microwave communication is suitable, although the equipment used was not. Recent developments in Europe are described, among which the CEPT decision to use the 5.8-GHz band with 3-dBW effective isotropically radiated power (EIRP) for vehicle to roadside communication in Europe is considered, as well as a specific solution for the multilane problem, called the pseudo-multilane solution. The pseudo-multilane solution provides a simple solution for vehicle to roadside communication without physical lane separation.<>
