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.
