V2V Path Loss Modeling at 26 GHz Based on Real-Traffic Measurements

Pawel Kryszkiewicz, Adrian Kliks, Pawel Sroka, Michal Sybis

Abstract

In this letter, we investigate single-slope path loss models complemented with shadowing effects in the context of vehicular communications. We present several models obtained based on extensive measurement campaigns with inter-vehicle transmission conducted at 26.555 GHz in real-traffic experiments, mainly along high-speed roads. Particular attention has been put on the impact of aerial characteristics (omnidirectional versus directional), surrounding environment (e.g., urban versus rural), and their mounting point on cars (at the rooftop, on the bumper, and below the car chassis). Finally, the effect of signal ducting and of the number of blocking cars has been analyzed and the decorrelation time has been discussed
