AI summary

In a wireless communication system, a transmitter that transmits data and a plurality of receivers wirelessly communicate with each other. The transmitter includes a first storage unit that stores first identification information of one of the receivers; a first communication unit that transmits the data; and a switching unit that switches a transmission destination of the data to another receiver having the first identification information stored in the first storage unit. The receiver includes a second storage unit that stores second identification information of a plurality of the transmitters; and a second communication unit that receives the data from the transmitter having the second identification information. Both the transmitter and the receiver store the first identification information and the second identification information to each other.
