Vehicle to vehicle RF propagation measurements

We present results from vehicle to vehicle RF propagation measurements centered at 900 MHz. We focus on determining delay spread probability distribution parameters (in particular the Rician K factor) and path loss rates. Our results are discussed with implications for the use of RF communication between automobiles in Intelligent Vehicle Highway Systems (IVHS). Our paper consists of a description of the IVHS concept along with a brief overview of wireless propagation theory. We then discuss our measured parameters with respect to implementing an RF transmission system between vehicles.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
