Summary:
Inter-vehicle communication system using 720 MHz band to prevent car crashes at an intersection has been proposed in Japan recently. In this paper, the propagation characteristics at an intersection surrounded by concrete block walls in residential area were analyzed by using the FDTD method for the first time. We investigated the influence of wall thickness and source locations on the propagation characteristics. As a result, the common wall thickness and source locations do not strongly affect the propagation loss. Furthermore, we analyzed the power delay profile by taking into consideration the structure of the concrete block walls.
