WLAN Radio Resource Management Configuration Commands

WLAN Radio Resource Management Configuration Commands

calibrate bandwidth (for FAT AP)

Function

The calibrate bandwidth command configures the calibration bandwidth.

The undo calibrate bandwidth command restores the default calibration bandwidth.

By default, the global calibration bandwidth is 20 MHz.

Format

calibrate 5g bandwidth { 20mhz | 40mhz }

undo calibrate 5g bandwidth

Parameters

Parameter

Description

Value

5g

Specifies the frequency band on which radio calibration is performed.

5g: Radios work at the 5 GHz frequency band.

-

20mhz | 40mhz

Specifies the calibration bandwidth.
NOTE:

-

Views

WLAN view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

The 5 GHz frequency band has richer spectrum resources. In addition to 20 MHz channels, APs working on the 5 GHz frequency band support 40 MHz channels. Larger-bandwidth channels mean higher transmission rates. However, at least three channels are required in radio calibration to achieve the optimal calibration effect. When configuring the calibration bandwidth, ensure that enough calibration channels are available for use.

You can use the calibrate bandwidth command to configure the calibration bandwidth and the calibrate channel-set command to configure calibration channels as prompted.

Configuration Impact

When the calibration bandwidth is changed, the device recalculates the calibration channels.

Precautions

When configuring 40-MHz calibration bandwidth, check whether channels of the corresponding bandwidth exist under the country code.

Example

# Set the global calibration bandwidth to 40 MHz.

<Huawei> system-view
[Huawei] wlan 
[Huawei-wlan-view] calibrate 5g bandwidth 40mhz

calibrate channel-set (for FAT AP)

Function

The calibrate channel-set command configures a calibration channel set.

The undo calibrate channel-set command restores the default calibration channel set.

By default, a global calibration channel set contains channels corresponding to global country codes.

NOTE:

The default calibration channels corresponding to the country code China do not include channels 36 to 64.

Format

calibrate { 2.4g | 5g } channel-set channel-value

undo calibrate { 2.4g | 5g } channel-set

Parameters

Parameter Description Value
2.4g | 5g
Specifies the frequency band on which radio calibration is performed.
  • 2.4g: Radios work on the 2.4 GHz frequency band.
  • 5g: Radios work on the 5 GHz frequency band.

-

channel-set channel-value

Specifies the calibration channel set.

The value is a character string. You can select calibration channels as prompted. If you select multiple channels, use commas (,) to separate channel names.

Views

WLAN view

Default Level

2: Configuration level

Usage Guidelines

You can run this command to specify a calibration channel set for an AP. The device selects channels from the channel set to calibrate. This reduces the burden on the AP.

NOTE:

To ensure a good calibration effect, you are advised to configure at least three calibration channels.

The 5 GHz frequency band has richer spectrum resources. In addition to 20 MHz channels, APs working on the 5 GHz frequency band support 40 MHz channels. Larger-bandwidth channels mean higher transmission rates. However, at least three channels are required in radio calibration to achieve the optimal calibration effect. When configuring the calibration bandwidth, ensure that enough calibration channels are available for use.

To specify a 40 MHz calibration channel, you need to specify two consecutive 20 MHz channels. To specify an 80 MHz calibration channel, you need to specify four consecutive 20 MHz channels. The combinations of 20 MHz channels making up the 40 MHz and 80 MHz channels are fixed. For details, see IOT Gateway Configuration Guide–Radio Resource Management–Radio Calibration.

You can also use the calibrate bandwidth command to configure the calibration bandwidth and the calibrate channel-set command to configure calibration channels as prompted.

NOTE:

When configuring a radio calibration set, avoid using radar channels.

The channels you configure must be supported by the terminals; otherwise, the terminals cannot discover wireless signals. For example, when the country code is set to China, 5 GHz channels 36, 40, 44, 48, 52, 56, 60, and 64 can be configured. However, most terminals do not support these channels currently. If these channels are configured, the terminals cannot discover wireless signals. In this case, you can configure 5 GHz channels 149, 153, 157, 161, and 165, which are supported by the terminals.

Example

# Configure a global calibration channel set composed of 40 MHz channels 149, 153, 157, and 161 on the 5 GHz frequency band.

<Huawei> system-view
[Huawei] wlan 
[Huawei-wlan-view] calibrate 5g bandwidth 40mhz
[Huawei-wlan-view] calibrate 5g channel-set 149,153,157,161

calibrate sensitivity (for FAT AP)

Function

The calibrate sensitivity command configures the radio calibration sensitivity for a device.

The undo calibrate sensitivity command restores the default radio calibration sensitivity.

Default Level

2: Configuration level

Usage Guidelines

There are three radio calibration modes:
  • Auto mode: The device periodically implements radio calibration at certain intervals (the interval is specified by interval and the default interval is 60 minutes).
  • Manual mode: Radio calibration is not automatically implemented by the device but manually triggered through the calibrate manual startup (for FAT AP) command.
  • Schedule mode: The device triggers radio calibration at the time specified by the parameter time.
The three modes cannot be configured simultaneously. You can choose any of the modes as required.

Example

# Set the radio calibration mode to auto.

<Huawei> system-view
[Huawei] wlan 
[Huawei-wlan-view] calibrate enable auto

# Set the radio calibration mode to schedule and set the time for scheduled radio calibration to 20:30:00.
