| Summary: | Vehicular Ad Hoc Networks (VANETs) are envisaged to be a critical building block of Smart Cities and Intelligent Transportation System (ITS) where applications for pollution and congestion reduction, vehicle mobility improving, accidents prevention and safer roads are some of the VANETs expected benefits into the Intelligent Vehicle Communications. Although there is a significant research effort in Vehicle-to-Infrastructure (V2I) communication radio channel characterization, the use of more general methods than theoretical and empirical models is required to understand more accurately the propagation phenomena in urban environments. In this work, a deterministic computational tool based on an in-house 3D Ray-Launching algorithm and standard IEEE 802.11p, is used to represent and analyze some large-scale and small-scale urban radio propagation phenomena for V2I, including the vehicles movement effects on each of the multipath components. Results show the impact of factors as distance, frequency, location of antenna transmitters (TX), obstacles and vehicles speed, in the V2I channel propagation. These results are useful for radio-planning Wireless Sensor Networks (WSNs) designers and deployment of urban Road Side Units (RSUs).
