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 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. 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 period of no transmission. Hence, stations do not lose its connectivity when an AP moves to a 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. channel.

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. can be configured for the 5 GHz Gigahertz. and secondary 5 GHz Gigahertz. radio profiles. It is configured using the zero-wait-dfs parameter in the rf dot11a-radio-profile and rf dot11a-secondary-radio-profile commands. This feature is disabled by default.

The following example configures 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 for the 5 GHz Gigahertz. radio profile:

(Instant AP) (config) # rf dot11a-radio-profile terre

(Instant AP) (RF Radio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. dot11a Radio Profile "terre") # zero-wait-dfs

Limitations

The following are the limitations of 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 due to the use of UTB filter on 5 GHz Gigahertz. radio:
