Abstract
In a wireless communication system in which a relay device provided on a mobile object communicates wirelessly with a plurality of communication devices present in places different from each other, each of the communication devices includes a communication device transmission unit which transmits test signals at a plurality of timings during a time frame when communication with the relay device is possible, a communication device reception unit which receives, from the relay device, communication situation information indicating communication situations at the plurality of timings, and a communication device control unit which controls the communication device transmission unit such that the communication device transmission unit communicates with the relay device at one of the plurality of timings, the communication situation of which is good and which is identified on the basis of the communication situation information, and the relay device includes a relay device reception unit which receives the respective test signals at the plurality of timings, a measurement unit which measures the respective communication situations at the time of reception of the test signals at the plura…
