Real-world evaluation of IEEE 802.11p for vehicular networks

Abstract

This paper presents a set of experiments, performed using an IEEE 802.11p physical layer implementation based on the open-source ath5k driver, in both line of sight (LOS) and non-line of sight (NLOS) conditions. The results are compared against theoretical models and simulation of the same scenarios with proper propagation and channel models. The communication range in LOS can reach values larger than 1Km, while in NLOS scenarios, this communication range is decreased to the order of hundreds of meters.
