Function

(AP group radio view) The antenna-gain command configures the antenna gain for all specified radios in an AP group.

(AP group radio view) The undo antenna-gain command restores the default antenna gain for all specified radios in an AP group.

(AP radio view) The antenna-gain command configures the antenna gain for an AP radio.

(AP radio view) The undo antenna-gain command cancels the configuration of the antenna gain on an AP radio. The antenna gain on the AP radio is then determined by that configured in the AP group radio view.

By default, no antenna gain is configured for AP radios.

The antenna gain of AP radios depends on AP types and working channels of AP radios. You can run the display ap-type { id type-id | type ap-type } command to check default antenna gains of radios of different AP types.

Value

antenna-gain

Specifies the antenna gain.

The value is an integer that ranges from –10 to 30, in dB.

Usage Guidelines

Usage Scenario

The antenna gain is the ratio of the power density produced by an antenna to the power density that should be obtained at the same point if the power accepted by the antenna were radiated equally. It can measure the capability for an antenna to receive and send signals in a specified direction, which is one of the most important parameters to select a BTS antenna. In the same condition, if the antenna gain is high, the wave travels far.

Precautions

  • The antenna gain of an AP radio configured using the command must be consistent with the gain of the antenna connected to the AP.

  • The antenna gain of an AP radio configured using the command takes effect only for external antennas. When an AP uses an external antenna, configure the antenna gain for the AP radio to be consistent with the gain of the external antenna connected to the AP.

  • The maximum antenna gain should comply with laws and regulations of the corresponding country. For details, see the Country Code & Channel Compliance Table. You can obtain this table at Huawei technical support website.

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

  • When the antenna gain of an AP is not an integer, the AC rounds the value off and delivers the integer antenna gain. For example, if the 2.4G antenna gain of an AP4130DN is 2.5 dB, the 5G antenna gain of 3 dB is displayed on the AC.

Example

# Set the antenna gain to 4 for radio 0 of AP 1.
