Title:
無線ＬＡＮシステムおよび干渉制御方法
Document Type and Number:
Japanese Patent JP7047719
Kind Code:
B2
Abstract:
Provided is a wireless LAN system in which an interference control signal transmitter that is provided in the surroundings of the wireless LAN base station and the wireless LAN terminal, and is configured to collect wireless environment information regarding the interfering AP/STA, and transmit, 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, determine the interference control signal transmitter whose communication area includes the interfering AP/STA based on the wireless environment information, and control 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.
