Characterisation of Radio Wave Propagation in Vehicular Environments Through Deterministic Methods

摘要

The interest for making vehicular transportation safer and more efficient has increased exponentially in recent years. To develop such vehicular communication systems, accurate models for the propagation channel are needed. This work analyzes the channel properties of different wireless communication systems within a vehicular communication environment with deterministic modeling. Three different frequencies have been analyzed: 868MHz, 2.4GHz and 5.9GHz. An in-house 3D Ray Launching code has been used for that purpose, taking into account the movement of the vehicles, leading to time and space-frequency models. Results present the great influence of multipath propagation in these type of environments, leading to a great aid in the identification of the optimal location of the transceivers, in order to minimize power consumption and increase overall service performance.
