Zero-Wait DFS

Dynamic Frequency Selection (DFS Dynamic Frequency Selection. DFS is a mandate for radio systems operating in the 5 GHz band to be equipped with means to identify and avoid interference with Radar systems.), a mandate for radio systems operating in the 5 GHz Gigahertz. band Band refers to a specified range of frequencies of electromagnetic radiation. to identify and avoid interference with Radar Radio Detection and Ranging. Radar is an object-detection system that uses radio waves to determine the range, angle, or velocity of objects. systems now supports zero-wait feature. When an 802.11 802.11 is an evolving family of specifications for wireless LANs developed by a working group of the Institute of Electrical and Electronics Engineers (IEEE). 802.11 standards use the Ethernet protocol and Carrier Sense Multiple Access with collision avoidance (CSMA/CA) for path sharing. radio detects radar, it vacates its channel and switches to another channel. This might result in a one minute outage. The zero wait DFS Dynamic Frequency Selection. DFS is a mandate for radio systems operating in the 5 GHz band to be equipped with means to identify and avoid interference with Radar systems. feature provides seamless change of channels and avoids the one minute outage. Hence, stations do not lose its connectivity when an AP moves to a DFS Dynamic Frequency Selection.
