PROBLEM TO BE SOLVED: To provide a radio communication system, capable of synchronizing the transmission of a plurality of video data with a simple structure.SOLUTION: A plurality of monitor cameras 10 are connected to one access point through radio communication means. Each monitor camera 10 comprises a communication control unit 13 for transmitting imaged and coded image data to the access point 20. The access point 20 comprises a preferential device determination unit 27 for identifying the monitor camera 10 that transmits the image data, measuring an image data reception speed for each monitor camera, and determining whether or not image data reception from a monitor camera having smaller reception speed than a reference speed is to be prioritized. A reception control unit 21 transmits, to the whole monitor cameras 10 in connection, a CTS packet indicating that data reception from the monitor camera 10 determined by the preferential device determination unit 27 is prioritized. On receiving the CTS packet, other monitor cameras 10 than indicated in the CTS packet suspend data transmission. |
