A wireless distribution system (WDS) is a system enabling the wireless bridging of access points in an IEEE 802 network. It allows an extended network to be created using wireless IEEE 802.11 (Wi-Fi) access points without the traditional requirement for wires to link them. The notable advantage of WDS over other solutions is that it preserves the MAC addresses of client frames across links between access points, thus mixtures of ethernet and WDS connections can be treated as a single network.

ActiveUS20100302966A1Reduce distractionsAvoid disturbanceWave based measurement systemsError preventionWeather radarCommunications system
An access point establishing a wireless LAN is constructed to have a monitor system ‘b’ for monitoring an available channel for communication, in addition to a communication system ‘a’. In the event of detection of radar / radio signals, the access point changes a communication channel used for wireless communication from a current active channel to the monitored channel. Each terminal belonging to the wireless LAN recognizes and follows this channel change by detection of a beacon broadcasted by the access point. In the case of non-detection of radar / radio signals for one minute at the monitored channel, the wireless communication is reestablished immediately at the monitored channel recognized as a CAC (channel availability check)-finished channel. This series of processing is also applicable to inter-access point communication, for example, communication in a WDS (wireless distribution system) mode. This arrangement desirably prevents the potential interruption of wireless communication in a 5 GHz frequency band for a significant period, in the event of detection of radar / radio signals, for example, a weather radar.
