Radio ID.


Channels used before and after switching.

Switch reason

Reason for channel switching.
  • calibration: channel switching caused by radio calibration
  • configuration: channel switching caused by configuration
  • dfs: channel switching performed to avoid radar channels
  • dfs recover: channel switching caused by DFS channel switchback
  • mesh: channel switching caused by channel negotiation on a Mesh network

Switch time

Time when channel switch occurred.

Item Description


Radio ID.


Channels before and after calibration.

PCH/CCH changes may be discontinuous for a radio.


Bandwidth before and after calibration.


Power before and after calibration.

PE/CE changes may be discontinuous for a radio.


Interference values before and after calibration.


Reason for triggering calibration.

  • Period recheck: periodic calibration
  • Bad env: environment deterioration
  • Non-Wi-Fi report: non-Wi-Fi report

    Only cloud APs support this parameter.

  • Rogue AP report: rogue AP report
  • Noise interfere: noise interference
  • Global plan: trial operation
  • AP online: The AP radio is on, the radio is switched (between 2.4 GHz and 5 GHz bands), the radio working mode changes, or the AP goes online.
  • AP offline: The AP radio is off, the radio is switched (between 2.4 GHz and 5 GHz bands), the radio working mode changes, or the AP goes offline.
  • Unknown: unknown reason


Time when calibration is triggered.

Trigger ID(Radio)

ID of the device (radio) that triggers radio calibration.
