Executive Summary

The authors present results of wideband (20 MHz) radio channel measurements at 5.9 GHz for the car-to-car channel in Rural, Highway, and Urban environments. Based on the measurements, corresponding path loss models for these environments are given. Power delay profiles are characterized using a simple model of a dominant path plus an exponential decay cluster, and statistics for these parameters are given. For all environments, Doppler spread statistics have been derived. Within the "NOW: Network on Wheels" project they have performed measurements of the wideband inter-vehicle radio channel at 5.9 GHz.
