Dynamic Frequency Selection (DFS)

Last updated Save as PDF OverviewDFS is the process of detecting radar signals that must be protected against interference from 5GHz (802.11a/n/ac/h) radiosby dynamicallyswitching the operating frequency of the 5GHz radio to one that does not interfere with radar.Transmit Power Control (TPC) is similarlyused to adapt the transmission power of a radio based on regulatory requirements and range information. Certified devices can enable DFS to take advantage of additional channel optionswhile listening for radar communication to dynamically update their radio settings, if necessary.DFS Events alerts by Access PointsAn access point may occasionally detect a radar signal and trigger the alert. When that happens, the 5GHz radio will disconnect its clients (clients on the 2.4GHz radio won't be disturbed), move to a different channel and continue to operate as expected. No actions need to be taken. For more details on the process, please check the section DFS Actions.Verifying DFS EventsGo to...
