Channel Metrics
The channel metrics graph displays channel quality, availability, and utilization metrics as seen by a spectrum
monitor or hybrid W-IAP. You can view the channel utilization data based on 2 GHz and 5 GHz radio channels.
The percentage of each channel that is currently being used by Wi-Fi devices, and the percentage of each
channel being used by non-Wi-Fi devices and 802.11 adjacent channel interference (ACI). This chart shows the
channel availability, the percentage of each channel that is available for use, and the current relative quality of
selected channels in the 2.4 GHz or 5 GHz radio bands. While spectrum monitors can display data for all
channels in their selected band, hybrid W-IAPs display data for a single monitored channel.
To view this graph, click 2.4 GHz in the Spectrum section of the dashboard.
Figure 103 Channel Metrics for the 2.4 GHz Radio Channel
To view this graph, click 5 GHz in the Spectrum section of the dashboard.
Figure 104 Channel Metrics for the 5 GHz Radio Channel
Channel Metrics shows the information displayed in the Channel Metrics graph.
Column Description
Channel A 2.4 GHz or 5 GHz radio channel.
Quality(%) Current relative quality of selected channels in the 2.4 GHz or 5 GHz radio bands, as
determined by the percentage of packet retries, the current noise floor, and the duty
cycle for non-Wi-Fi devices on that channel.
Availability(%) The percentage of the channel currently available for use.
Utilization(%) The percentage of the channel being used.
WiFi Util(%) The percentage of the channel currently being used by Wi-Fi devices.
Interference Util(%) The percentage of the channel currently being used by non-Wi-Fi interference plus Wi-
Fi adjacent channel interference (ACI)
