Figure 21 Channel Availability Map for Clients
AppRF
The AppRF link displays the application traffic summary for W-IAPs and client devices. The AppRF link in the
activity panel is displayed only if AppRF visibility is enabled in the System window. For more information on
application visibility and AppRF charts, see Application Visibility on page 242.
Spectrum
The spectrum link (in the Access Point view) displays the spectrum data that is collected by a hybrid AP or by a W-
IAP that has enabled spectrum monitor. The spectrum data is not reported to the Virtual Controller.
The spectrum link displays the following:
l Device list - The device list display consists of a device summary table and channel information for active non
Wi-Fi devices currently seen by a spectrum monitor or hybrid AP radio.
l Channel Utilization and Monitoring - This chart provides an overview of channel quality across the spectrum. It
shows channel utilization information such as channel quality, availability, and utilization metrics as seen by a
spectrum monitor for the 2.4 GHz and 5 GHz radio bands. The first bar for each channel represents the
percentage of air time used by non Wi-Fi interference and Wi-Fi devices. The second bar indicates the channel
quality. A higher percentage value indicates better quality.
l Channel Details - When you move your mouse over a channel, the channel details or the summary of the 5 GHz
and 2.4 GHz channels as detected by a spectrum monitor are displayed. You can view the aggregate data for
each channel seen by the spectrum monitor radio, including the maximum AP power, interference and the Signal-
to-Noise and Interference Ratio (SNIR). Spectrum monitors display spectrum analysis data seen on all channels
in the selected band, and hybrid W-IAPs display data from the one channel they are monitoring.
For more information on spectrum monitoring, see Spectrum Monitor on page 309.
