WIRELESS COMMUNICATIONS SYSTEM CONTROL METHOD AND PROGRAM

摘要

A wireless communications system is provided with a plurality of wireless communications apparatuses for respective traffic lanes on a road that perform wireless communications with a vehicle travelling in any of the traffic lanes. Each of the wireless communications apparatuses performs transmission and reception with the vehicle travelling in the corresponding traffic lane by shifting the timing of a transmission/reception control period in which the transmission and reception with the vehicle is performed in a control channel having a first frequency and the timing of a transmission/reception control period in which the transmission and reception with the vehicle is performed in a service channel having a frequency that is different from the frequency of the first frequency from the timings for the other wireless communications apparatuses.
