Function

(AP group radio view) The coverage distance command configures the radio coverage distance parameter for all specified radios in an AP group.

(AP group radio view) The undo coverage distance command restores the default radio coverage distance parameter for all specified radios in an AP group.

(AP radio view) The coverage distance command configures the radio coverage distance parameter for an AP radio.

(AP radio view) The undo coverage distance command cancels the configuration of the radio coverage distance parameter on an AP radio. The radio coverage distance parameter on the AP radio is then determined by that configured in the AP group radio view.

By default, the radio coverage distance parameter is 3 (unit: 100 m) for all radios.

Parameters

Parameter

Description

Value

distance

Specifies the radio coverage distance parameter.

Each distance parameter corresponds to a group of slottime, acktimeout, and ctstimeout values. You can configure the distance parameter based on the AP distance. APs adjust the values of slottime, acktimeout, and ctstimeout values based on the distance parameter.

The value is an integer that ranges from 1 to 400, in 100 meters.

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

In actual application scenarios, two APs may be connected over dozens of meters to dozens of kilometers. Due to different AP distances, the time to wait for ACK packets from the peer AP varies. A proper acktimeout value can improve data transmission efficiency between APs.

You can configure the radio coverage distance parameter based on distances between APs and the APs automatically adjust the values of slottime, acktimeout, and ctstimeout based on the configured distance parameter to improve data transmission efficiency.

Precautions

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

Example

# Set the radio coverage distance parameter to 2 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] coverage distance 2
