Configure Smart RF Basic Settings

Procedure

  1. Select Policies > Smart RF.
    A list of existing Smart RF policies opens. Review existing Smart RF policies:
    Policy Displays the name assigned to the Smart RF policy when it was initially created. The name cannot be modified as part of the edit process
    Status A green check mark indicates that Smart RF has been activated for the listed policy. A red “X” designates the policy as being deactivated
    Interference Recovery A green check mark indicates that interference recovery has been activated for the listed policy. A red “X” designates the policy as being deactivated
    Coverage Hole Recovery A green check mark indicates that coverage hole recovery has been activated for the listed policy. A red “X” designates the policy as being deactivated
    Neighbor Recovery A green check mark indicates that neighbor recovery has been activated for the listed policy. A red “X” designates the policy as being deactivated
  2. Select to add a new Smart RF policy or to edit an existing Smart RF policy.
    The Add Policy window opens for new policy. The Basic Settings dashboard opens to edit basic configuration setting.
  3. Assign a unique policy name and select Add.
    A new Smart RF policy is added and the Basic Settings dashboard opens.
  4. Define the following basic settings:
    Sensitivity Select an option from the drop-down list box to configure Smart RF sensitivity. The options include:
    • Custom
    • High
    • Low
    • Medium

    The Custom option allows an administrator to adjust the parameters and thresholds for Interference Recovery, Coverage Hole Recovery, and Neighbor Recovery. Using the Low, Medium (recommended), and High settings allows these features to be utilized
    Policy Enable Select Policy Enable to enable Smart RF for immediate inclusion within an RF Domain. Smart RF is selected by default
    Interference Recovery Select Interface Recovery to enable compensations from neighboring radios when radio interference is detected. When interference is detected, Smart RF first determines the power increase needed based on the signal to noise ratio for a client (as seen by the access point radio). If a client‘s signal to noise value is above the threshold, the transmit power is increased until the signal to noise rate falls below the threshold. This option is selected by default
    Coverage Hole Recovery Select Coverage Hole Recovery to enable coverage compensation from neighboring radios when a radio coverage hole is detected within the Smart RF supported radio coverage area. When a coverage hole is detected, Smart RF first determines the power increase needed based on the signal-to-noise ratio for a client as seen by the access point radio. If a client‘s signal-to-noise value is above the threshold, the transmit power is increased until the signal-to-noise rate falls below the threshold. This option is selected by default
    Neighbor Recovery Select Neighbor Recovery to enable Neighbor Recovery when a failed radio is detected within the Smart RF supported radio coverage area. Smart RF can provide automatic recovery by instructing neighboring APs to increase their transmit power to compensate for the coverage loss. Neighbor Recovery is selected by default when the sensitivity setting is Medium
  5. Configure Calibration Assignment per area by selecting Enable per Area or Enable per Floor.
  6. Configure Smart Sensor parameters to activate auto-provisioning of access points as sensors.
    It is important to get the right balance between the number of APs functioning as sensors and APs providing WLAN service in a larger deployment. Smart sensor automates provisioning of APs as sensors without compromising network security.
    Enable Smart Sensor Select Enable Smart Sensor to activate auto-provisioning of access points as sensors. Select this option to automatically turn on the sensor radios on 1/3rd of the deployed access points
    Note: By default, Smart RF selects and provisions only tri-radio APs as sensors. To enable Smart RF to select dual-radio APs, configure the Smart RF policy through the CLI and run the no > smart-sensor > tri-radio-only command
    Auto Trigger Select Auto Trigger to enable smart-sensor settings automatically
    Note: The smart-sensor calibration is auto-triggered when smart-sensor is enabled for the first time. In case a re-calibration is required, manually issue the trigger-smartsensor on command through the CLI to activate the algorithm. Re-calibration maybe needed if you change the number of APs deployed or the AP deployment pattern within the RF Domain
    Algorithm Cell Size Select Algorithm Cell Size to enable the use of an algorithmic function to identify the sensor APs.
    The WiNG Smart-sensor feature uses an algorithm to provision APs as sensor within a site (RF Domain). The algorithm creates a cluster of cells based on inputs from the Smart-RF neighbor table. Each cell in the cluster represents an AP and adjacent cells are the AP's neighbor. The algorithm then identifies APs with best coverage area and provisions them as sensors. However, the algorithmic calculations vary depending on the cell size. The current implementation provides two algorithms based on the cell size (dense, none, or sparse). Select the algorithm best suited for your deployment:
    • dense - Selects the algorithm best suited for dense deployments. In dense deployments, the cell-size is small, with APs deployed close to each other
    • none - No cell size is selected
    • sparse - Selects the algorithm best suited for sparse deployments. In sparse deployments, the cell-size is large, with APs deployed far apart from each other
    Smart Band Select the radio band frequency to work with smart sensor
    Tri-Radio Select to enable smart senor only on tri-radio access points
  7. Select Save to configure and update Smart RF basic settings for this policy.
