The following figure shows the client distribution details for an AP radio.
Figure 15 Client Distribution on AP Radio
On clicking a client in the Clients tab and the Client Match link, a graph is drawn with real-time data points for
an AP radio map. When you hover the mouse on the graph, details such as RSSI, channel utilization details, and
client count on each channel are displayed.
The following figure shows the client view heatmap for an AP radio:

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 261.
Spectrum
The spectrum link (in 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
