Caracterización de las pérdidas de propagación en escenarios vehiculares bajo condiciones LOS y NLOS a 700 MHz y 5.9 GHz

Abstract

Vehicular-to-vehicular (V2V) communications are receiving considerable attention due to the introduction of the intelligent transportation system (ITS) concept, enabling smart and intelligent driving technologies and applications. To design and evaluate ITS applications, the knowledge of the propagation channel characteristics is vital, in particular the path loss which has an important influence in the final performance of the communications system. From a narrowband channel measurements campaign carried out in urban areas, with different road traffic densities, and expressway environments, this paper analyzes the path-loss in terms of the transmitter (Tx) and receiver (Rx) separation distance at 700 MHz and 5.9 GHz. Based on a linear slope model, values for the path loss exponent and the standard deviation of shadowing are reported.
