calibrate max-tx-power

Function

The calibrate max-tx-power command sets the maximum transmit power that can be adjusted through radio calibration.

The undo calibrate max-tx-power command restores the default maximum transmit power that can be adjusted through radio calibration.

By default, the maximum transmit power that can be adjusted through radio calibration is 127 dBm.

Usage Guidelines

Usage Scenario

After radio calibration is enabled, an AP uses the Transmit Power Control (TPC) algorithm to calculate the transmit power to be adjusted based on detected neighbor information. If the transmit power to be adjusted calculated using the TPC algorithm is to large, signal interference between APs may occur. You can run the calibrate max-tx-power command to set the maximum transmit power that can be adjusted through TPC.

Precautions

The maximum radio calibration power must be larger or equal to the minimum radio calibration power. You can run the calibrate min-tx-power command to set the minimum calibration power.

You can adjust the maximum and minimum calibration powers using the calibrate max-tx-power and calibrate min-tx-power commands. The valid power after radio calibration is between the two values.

Example

# Set the maximum transmit power that can be adjusted through radio calibration to 30 dBm.
