4. Refer to the Basic Settings field to enable a Smart RF policy and define its sensitivity and
detector status.
5. Refer to the Calibration Assignment field to define whether Smart RF Calibration and radio
grouping is conducted by area or floor. Both options are disabled by default.
Sensitivity Select a radio button corresponding to the desired Smart RF sensitivity. Options include Low,
Medium, High and Custom. Medium, is the default setting. 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 still
allow these features to be utilized.
SMART RF Policy Enable Select the Smart RF Policy Enable check box to enable this Smart RF policy for immediate support
or inclusion with a RF Domain. Smart RF is enabled by default.
Interference Recovery Select the check box to enable Interference Recovery from neighboring radios and other sources of
WiFi and non-WiFi interference when excess noise and interference is detected within the Smart RF
supported radio coverage area. Smart RF provides mitigation from interference sources by
monitoring the noise levels and other RF parameters on an Access Point radio’s current channel.
When a noise threshold is exceeded, Smart RF can select an alternative channel with less
interference. To avoid channel flapping, a hold timer is defined which disables interference
avoidance for a specific period of time upon detection. Interference Recovery is enabled by default.
Coverage Hole Recovery Select the check box to enable Coverage Hole Recovery when a radio coverage hole is detected
within the Smart RF supported radio coverage area. When 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.
Neighbor Recovery Select the check box 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 enabled by default when the sensitivity setting is medium.
