Abstract: A transmission data controller determines a frequency bandwidth according to a relay apparatus position, the frequency bandwidth being used for a first signal transmitted from a first communication apparatus, on the basis of information regarding the number of first communication apparatuses with which a relay apparatus communicates at the relay apparatus position. The transmission data controller transmits band information indicating a frequency band selected from radio frequency bands that can be used for the first signal on the basis of the determined frequency bandwidth to the first communication apparatus. The first communication apparatus transmits the first signal having a frequency included in the frequency band indicated by the band information. The relay apparatus acquires waveform data of the first signal transmitted by the first communication apparatus, and transmits the acquired waveform data to a second communication apparatus by a second signal.
