• Hover the mouse over a widget to display tool tip information.
Configure Smart Poll from the device group Advanced Settings dialog. You can also override Smart Poll
configuration for a selected AP.

Smart RF Widgets
The following widget reports for each radio are available from the AP Smart RF tab:
Note
The Smart RF tools reflect data available for channels that are selected in the Channel Plan
when Smart RF is enabled on the radio. For more information, see Channel and Power
Settings on page 165.
• Mitigation. Mitigation action taken by Smart RF to improve the network:
◦ Channel Change — The channel of an AP radio was changed
◦ Power Change — The power of an AP radio was changed
◦ Select Shutdown — AP radio shutdown
◦ Coverage Hole — AP reacts to holes in AP coverage
• Channel Energy. Displays the amount of interference detected by each radio on each channel and
indicates the source of the interference:
◦ Neighbor Wi-Fi for APs
◦ External Wi-Fi for non-neighbor sources of Wi-Fi interference
◦ Non Wi-Fi Energy for interference that is not generated by a Wi-Fi signal
• Channel Inspector. Provides a high level of visibility as to the occupancy of the RF spectrum around
a particular AP. The following data is provided on the widget:
◦ Frequency. Radio Frequency channels with the beacon channel (primary) denoted with brackets.
The following is an 80MHz channel example showing [5220] as the beacon channel. 44: (5180
5200 [5220] 5240).
◦ Noise. Channel noise measured in Decibel-milliwatts (dBm).
◦ Ranking. Indicates the best operating channel based on a 5-star ranking. This ranking is relative
to the channels that are available. The higher the rank the more desirable the channel. The
ranking algorithm considers the following parameters:
▪ noise level
▪ overlap count
▪ co-channel count
▪ adjacent AP count
◦ Overlap. Number of APs on overlapping channels. Applicable for 40MGz and 80MGz channels
only. The 20MGz channel is designated as the primary and the other channels are designated as
extension channels (secondary). If the primary channel of one AP is the same as the extension
channel of another AP it is considered overlapping. Overlapping is the worst type of interference.
◦ Co-Channel. Number of co-channel APs. APs on the same channel as the target AP are
competing. Using Distributed Control Function (DCF) collisions are avoided because the APs
