Reference Guide

Each channel and power parameter is fully configurable within the Smart RF Policy, enabling an
administrator to tweak the system to suit their specific wireless deployment needs. For example,
administrators can modify the Smart RF policy to exclude DFS channels or lower the minimum and
maximum power values for high-density deployments. By default, Smart RF will assign radios a power
value between 4 dBm and 17 dBm, a 20 MHz channel to each 2.4 GHz radio, and a 80 MHz channel to
each 5 GHz and 6 GHz radio.

Certain 5 GHz channels are subject to FCC / ETSI Dynamic Frequency Selection (DFS) regulations. If a
Smart RF-enabled radio is on a channel subject to DFS, it will switch channels if radar is detected on the
assigned 5 GHz channel.
Recovery Features
Smart RF supports self-healing features by monitoring the RF environment in real-time and provides
automatic mitigation from potentially problematic events such as:
• neighbor interference
• non-Wi-Fi interference (noise)
• external Wi-Fi interference
• coverage holes
• radio failures
Smart RF employs self-healing to maintain wireless client performance and wireless coverage during
dynamic RF environment changes that typically require manual intervention to resolve.
Note
The Smart RF recovery features are intended to provide a temporary measure until a
permanent fix is applied.
For example, if a remote site is experiencing constant Coverage Hole Recovery events for wireless
clients within a specific coverage area, the administrator will need to re-survey the area and determine if
deploying an additional AP or dierent antennas can remediate the coverage problem. Likewise, if an
