Vehicle-Ground Fast Link Handover Configuration Commands

Vehicle-Ground Fast Link Handover Configuration Commands

Command Support

Only the S5720HI supports WLAN-AC commands.

antenna-output

Function

The antenna-output command configures an output mode of a 2.4G/5G antenna.

The undo antenna-output command restores the default output mode of a 2.4G/5G antenna.

By default, a 2.4G/5G antenna uses split output.

Format

antenna-output { split | combine }

undo antenna-output

Parameters

Parameter

Description

Value

split Indicates the split mode of a 2.4G/5G antenna. -
combine Indicates the combination mode of a 2.4G/5G antenna. -

Views

AP system profile view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

In train-ground communication scenarios, you can use the antenna-output split command to configure the split mode of a 2.4G/5G antenna. The antenna uses either the 2.4 GHz radio to provide wireless coverage in the carriage, or the 5 GHz radio to provide wireless bridging between carriages.

In train-ground communication scenarios, you can use the antenna-output combine command to configure the combination mode of a 2.4G/5G antenna. The antenna uses the 2.4 GHz and 5 GHz radios to simultaneously provide wireless bridging between carriages.

Precautions

Only the AP9132DN and AP8182DN support this function.

Example

# Configure the combination mode of a 2.4G/5G antenna.

<HUAWEI> system-view
[HUAWEI] wlan 
[HUAWEI-wlan-view] ap-system-profile name apsys1
[HUAWEI-wlan-ap-system-prof-apsys1] antenna-output combine

client-mode enable

Function

The client-mode enable command enables the Mesh client mode.

The undo client-mode enable command disables the Mesh client mode.

By default, the Mesh client mode is disabled.

Format

client-mode enable

undo client-mode enable

Parameters

None

Views

Mesh profile view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

If the Mesh client is enabled for vehicle-mounted APs, trackside APs must also have the Mesh client enabled to set up a Mesh link.

Precautions

You cannot configure the Mesh client mode and bind the Mesh profile to a Mesh handover profile at the same time.

Example

# Enable the Mesh client mode for Mesh profile test.

<HUAWEI> system-view
[HUAWEI] wlan
[HUAWEI-wlan-view] mesh-profile name test
[HUAWEI-wlan-mesh-prof-test] client-mode enable

By default, the location-based enhanced link handover algorithm is disabled.

Format

location-based-algorithm enable

undo location-based-algorithm enable

Parameters

None

Views

Mesh handover profile view

Default Level

2: Configuration level

Usage Guidelines

After the location-based enhanced link handover algorithm is enabled, the vehicle-mounted AP will switch the active link to the nearest trackside AP that meets handover requirements.

In vehicle-ground communication scenarios, signals of a trackside AP distant from a train may be temporarily better than the trackside AP near the train due to radio environment changes. If an active link handover occurs at this time, the active link may be incorrectly switched to the distant trackside AP. To prevent incorrect handovers and improve vehicle-ground communication quality, you can use the location-based enhanced link handover algorithm. This algorithm requires that trackside APs be named in ascending or descending order of sequence numbers.

Trackside APs should be named in head-name_sequence-number format. head-name describes track line information and can be different for trackside APs on the same track. It is recommended that you set the same head-name for APs on a track to differentiate tracks. sequence-number of APs along a track must be in descending or ascending order. The sequence numbers of trackside APs can be set with unequal steps. head-name and sequence-number are separated using an underline (_), for example, L1_001, L1_002, L1_005, L1_010.

Example

# Enable the location-based enhanced link handover algorithm.
