Each of a plurality of wireless communication apparatuses determines a factor that indicates wireless communication congestion and compares the factor that indicates wireless communication congestion with a predetermined first threshold value. Each wireless communication apparatus then judges, by means of transmission power set values that are received from other wireless communication apparatuses, whether the transmission power of the wireless communication apparatuses is at the same level as or at a lower level than that of its own wireless communication apparatus. The wireless communication apparatus lowers the transmission power set value by one level when the transmission power of other wireless communication apparatuses is at the same level as or at a lower level than that of its own wireless communication apparatus and when the factor that indicates wireless communication congestion exceeds a first threshold value. |
