A communication system capable of controlling transmission power in an environment in which a wireless device capable of controlling transmission power and a wireless device capable of controlling transmission power coexist is provided. A communication system includes access points. The access points 11, 12, 15 to 20 are access points that control transmission power, and the access points 13 and 14 are access points that do not control transmission power. The access points 11, 12, 15 to 20 transmit and receive data packets using transmission power smaller than the maximum transmission power Pmax in the doTPC time zone of one slot. The access points 13 and 14 transmit and receive data packets with the maximum transmission power Pmax in the no TPC time zone of one slot. [Selection] Figure 14 |
