| Abstract(in English) | In a near future, automated driving will be realized, in which vehicles will be in constant communication with communication infrastructure and traffic control centers. As a means of communication, the 5th generation mobile communication system (5G) and ITS communication systems are expected to be used. In the 5G system, the sub-millimeter wave band (28 GHz) is planned to be used in addition to the sub 6 GHz band. In addition, the use of 900 MHz is being considered for ITS communications. However, the service area of road-to-vehicle and inter-vehicle communications in urban areas is greatly affected by the frequency, urban structure, and base station structure. In this paper, we investigate the relationship between the number of diffraction and the accuracy in the simulation by simulating the radio propagation using the structure data of suburban and urban areas. In addition, we compared the results of simulations for suburban and urban areas, and investigated the relationship between the number of buildings and the calculation time. |
