Wireless: Radio Resource Management and Dynamic Channel Selection
05/29/2020 2 3800
SonicOS 188.8.131.52 provides Radio Resource Management and Dynamic Channel Selection enhancements to Access Points settings.
NOTE: Radio Resource Management is supported on SonicWall access points that have a dedicated scan radio, including SonicWave 231c, 231o, 432e, 432i, and 432o. The RRM feature is not supported on SonicWave 224w or on SonicPoints.
You can navigate to MANAGE | Connectivity | Access Points | Radio Resource Management tab to configure these options.
Radio Resource Management and Dynamic Channel Selection Options and Values:
Enable Radio Resource Management - RRM
Enable this option to activate the settings for Station Quality Threshold and Radio Quality Threshold. This option is disabled by default.
Station Quality Threshold (1-50)
Health index to track and assess the status of wireless client connections, from 1 to 50. A higher index value means the wireless station is connected with higher data rate and less packet drop. Wireless clients will be disconnected if station quality drops below the configured threshold. • Minimum value = 1 • Maximum value = 50 • Default value = 20
Radio Quality Threshold (1-50)
Health index to track and assess the status of radio band utilization, which varies between 1 and 50. A higher index value means radio band utilization is lower with less packet drop. The radio transmit power will be lowered if the radio quality drops below the configured threshold. • Minimum value = 1 • Maximum value = 50 • Default value = 20
Dynamic Channel Selection Mode DCS Mode: Global / Local
DCS Mode supports two settings for automatic channel selection: • Global Mode – Firewall assigns proper channel for all SonicWaves according to information received from all SonicWaves. • Local Mode – SonicWave finds the best channel according to the information from itself.
Auto Channel Enable: 2.4GHz Radio DCS Scheme 5GHz Radio DCS Scheme
2.4GHz or 5GHz Radio DCS Scheme options are: • Safe Mode (CGI value 0) SonicWaves switch to a better channel only without clients connected. This is conservative mode. • Steady Mode (CGI value 1) SonicWaves seek a better channel periodically in the background. This is moderate mode. • Swift Mode (CGI value 2) SonicWaves switch to a better channel as soon as noise/interference becomes high on the current channel. This is aggressive mode. Safe Mode is the default.
