Claim 5:
6. An interference control method of a wireless LAN system in which, in the surroundings of a wireless LAN base station and a wireless LAN terminal that perform communication with each other, there is an interfering AP/STA that is to transmit an interference signal, the method comprising the steps of: an interference control signal transmitter provided in the surroundings of the wireless LAN base station and the wireless LAN terminal collecting wireless environment information regarding the interfering AP/STA, and transmitting, to the interfering AP/STA, an interference control signal that is to be used to set a transmission waiting period; and an interference control signal management device configured to collect the wireless environment information from the interference control signal transmitter determining the interference control signal transmitter whose communication area includes the interfering AP/STA based on the wireless environment information, and controlling the determined interference control signal transmitter to transmit the interference control signal to be used to set the transmission waiting period that corresponds to a length of time of the communication between the wireless LAN base station and the wireless LAN terminal, wherein while the interfering AP/STA that has received the interference control signal sets the transmission waiting period, the wireless LAN base station and the wireless LAN terminal preferentially perform communication.
