calibrate min-tx-power

calibrate min-tx-power

Function

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

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

By default, the minimum transmit power that can be adjusted through radio calibration is 9 dBm.

Format

Parameters

Parameter

Description

Value

min-tx-power power

Specifies the minimum transmit power that can be adjusted through radio calibration.

The value is an integer that ranges from 1 to 127, in 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 calculated using the TPC algorithm is too small, radio coverage requirements may not be met. You can run the calibrate min-tx-power command to set the minimum 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 max-tx-power command to set the maximum 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. If the values are set improperly, the maximum and minimum calibration power settings may fail to take effect.
  • If the maximum calibration power is smaller than the minimum transmit power of an AP, the minimum transmit power takes effect. For example, if the minimum transmit power of an AP on the 2.4 GHz band is 9 dBm and the maximum calibration power is set to 8 dBm, the transmit power on the 2.4 GHz band is 9 dBm after radio calibration.
  • If the minimum calibration power is larger than the maximum transmit power of an AP, the maximum transmit power takes effect. For example, if the maximum transmit power on the 2.4 GHz band is 21 dBm and the minimum calibration power is set to 25 dBm, the transmit power on the 2.4 GHz band is 21 dBm after radio calibration.

Example

# Set the minimum transmit power that can be adjusted through radio calibration to 10 dBm.
