Configuring an Adaptive Modulation and Coding (AMC) Algorithm for a Radio
Context
Radios need to adjust the AMC algorithm
according to different scenarios to deliver the optimal user experience.
Three AMC algorithms are available:
- auto-balance: applicable to most wireless scenarios
- high-stability: applicable to scenarios with continuous interference.
- high-throughput: applicable to scenarios with good wireless signals and non-continuous interference.
Pre-configuration Tasks
Before configuring the AMC algorithm, perform the task of Basic WLAN Service Configuration.
Procedure
- Run system-view
The system view is displayed.
- Run wlan ac
The WLAN view is displayed.
- Run rrm-profile name profile-name
An RRM profile is created, and the RRM profile view is displayed.
- Run amc-policy { auto-balance | high-stability | high-throughput }
An AMC algorithm is configured for the radio.
By default, a radio uses the AMC algorithm auto-balance.
- Run quit
Return to the WLAN view.
- Bind the RRM profile to a radio profile.
- Run the radio-2g-profile name profile-name or radio-5g-profile name profile-name command to enter the 2G or 5G radio profile view.
- Run the rrm-profile profile-name command to bind the RRM profile to the 2G or 5G radio profile.
- Run the quit command to return to the WLAN view.
- Bind the radio profile to an AP group or a specific AP. For the detailed procedure, see Binding a Radio Profile.
- Run quit
Return to the WLAN view.
- Run commit { all | ap-name ap-name | ap-id { ap-id1 [ to ap-id2 ] } &<1-10> }
Configurations are delivered to APs.
Verifying the Configuration
- Run the display rrm-profile name profile-name command to check the the AMC algorithm configured for radios in the RRM profile.
- Run the display radio-2g-profile name profile-name command to check the RRM profile bound to the 2G radio profile.
- Run the display radio-5g-profile name profile-name command to check the RRM profile bound to the 5G radio profile.
