A communication system includes transmission apparatuses and a reception apparatus. Each transmission apparatus includes a data input processing unit to which data is input, a first controller that performs a control process for transmitting the data, and a first wireless communication processing unit that transmits the data to the reception apparatus according to the control process performed by the first controller. The first controller performs a control process for causing another transmission apparatus to transmit data input to the other transmission apparatus to the reception apparatus. The reception apparatus includes a second wireless communication processing unit that receives data from one of the transmission apparatuses, a second controller that performs a control process for outputting the received data, and a data output processing unit that outputs the received data according to the control process performed by the second controller.
