Summary of Radio Resource Management Configuration Tasks

Table 11-1 describes the configuration tasks of radio resource management.

Table 11-1  Radio resource management configuration tasks




Configure interference detection

Wireless channels of WLANs are vulnerable to interference in surrounding radio environments, and the service quality is therefore degraded. If interference detection is configured, a monitor AP can know the radio environment in real time and report alarms in a timely manner.

Interference detection enables an AP to detect AP co-channel interference, AP adjacent-channel interference, and STA interference.
  • AP co-channel interference: Two APs working on the same frequency band interfere with each other. For example, on a large-scale WLAN (a university campus network), different APs often use the same channel. When there are overlapping areas among these APs, co-channel interference exists, degrading network performance.

  • AP adjacent-channel interference: Two APs with different center frequencies have overlapping areas, resulting in adjacent-channel interference. Therefore, if APs are placed too close to each other or they have strong signals, more noise will be produced, degrading network performance.

  • STA interference: If there are many STAs that are managed by other APs around an AP, services of the STAs managed by the local AP may be affected.

Configuring Interference Detection

Configure radio calibration

On a WLAN, operating status of APs is affected by the radio environment. For example, a large-power AP can interfere with adjacent APs if they work on overlapping channels. The radio calibration function can dynamically adjust channels and power of APs to ensure that the APs work at the optimal performance.

Configuring Radio Calibration

Configure band steering

When an AP and STA support both 5 GHz and 2.4 GHz frequency bands, the AP can steer the STA to the 5 GHz radio first.

Most STAs support both 5 GHz and 2.4 GHz frequency bands and usually associate with the 2.4 GHz radio by default when connecting to the Internet. To connect the STAs to the 5 GHz radio, you need to manually select the 5 GHz radio. When the 2.4 GHz frequency band has many users or severe interference, the 5 GHz frequency band can provide better access service for wireless users. The band steering function enables APs to steer STAs to the 5 GHz radio first.

Configuring Band Steering

Configure smart roaming

This configuration applies to scenarios where STAs connected to APs have weak signals or low rates. It can improve service experience of online STAs.

The smart roaming function allows an AP to send a Disassociation frame to STAs whose signal strength or access rate is lower than the specified threshold so that the STA can reconnect to the network.

Configuring Smart Roaming

Configure automatic per packet power adjustment

You can configure automatic per packet power adjustment on WLANs with good signal coverage to reduce AP power consumption and interference to surrounding devices.
