Properties and Applications of the Suburban Vehicle-to-Vehicle Propagation Channel at 5.9 GHz

We describe a system capable of making channel measurements as a function of location while the vehicles are in motion to study the properties of the vehicle-to-vehicle wireless channel. We present results from on-road experimental tests in suburban areas of Pittsburgh. The dependence of Doppler spread on both velocity and vehicle separation is discussed. We introduce the speed-separation (S-S) diagram as a new tool for understanding and estimating Doppler spread in the vehicle-to-vehicle environment.
