eirp

Function

(AP group radio view) The eirp command configures the transmit power for all specified radios in an AP group.

(AP group radio view) The undo eirp command restores the default transmit power for all specified radios in an AP group.

(AP radio view) The eirp command configures the transmit power for an AP radio.

(AP radio view) The undo eirp command cancels the configuration of the transmit power on an AP radio. The transmit power on the AP radio is then determined by that configured in the AP group radio view.

By default, the transmit power of a radio is 127 dBm. The transmit power that takes effect on APs is related to the AP type, country code, channel, and channel bandwidth. It is the maximum transmit power supported by the AP radio under the current configuration. Run the display radio { ap-name ap-name | ap-id ap-id } command to check the maximum value.

Usage Guidelines

Usage Scenario

You can configure the transmit power for a radio based on actual network environments, enabling radios to provide the required signal strength and improving signal quality on WLANs.

Precautions

The value of antenna-gain in the antenna-gain antenna-gain command must be consistent with the gain of the antenna connected to an AP.

If automatic transmit power selection is enabled by running the calibrate auto-txpower-select enable command, the transmit power configured by running the eirp command does not take effect. The automatically selected transmit power prevails.

If automatic transmit power selection is disabled by running the calibrate auto-txpower-select disable command, the transmit power configured by running the eirp command takes effect depending on the following principles:

The actual transmit power of an AP radio is determined by the configured transmit power of the radio, requirements of local laws and regulations, as well as the transmit power range supported by the AP. The actual transmit power of a radio cannot exceed the maximum transmit power required by local laws and regulations.

If the configured transmit power of a radio is in compliance with local laws and regulations and within the transmit power range supported by the AP, the configured transmit power is the actual transmit power of the radio.
If the configured transmit power of a radio is smaller than the minimum transmit power supported by the AP, the smaller one between the minimum transmit power supported by the AP and maximum transmit power required by local laws and regulations is the actual transmit power of the radio.
If the configured transmit power of a radio is larger than the maximum transmit power supported by the AP, the smaller one between the maximum transmit power supported by the AP and maximum transmit power required by local laws and regulations is the actual transmit power of the radio.

The configuration in the AP radio view has a higher priority than that in the AP group radio view.

Example

# Set the transmit power to 30 dBm for radio 0 of AP 1.

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] ap-id 1
[HUAWEI-wlan-ap-1] radio 0
[HUAWEI-wlan-radio-1/0] eirp 30
Info: The EIRP value takes effect only when automatic transmit power selection i
s disabled, and the value depends on the AP specifications and local laws and re
gulations.
