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.
PrecautionsThe 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.
- 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.
