The radios on groups of APs can be converted to dedicated spectrum monitors or hybrid APs via the AP group’s
dot11a and dot11g radio profiles. Individual APs can also be converted to spectrum monitors through the AP’s
spectrum override profile.

The Spectrum Analysis section of the WebUI includes the Spectrum Monitors, Spectrum Session Log, and
Spectrum Dashboards windows.
 Spectrum Monitors: A spectrum analysis client is any laptop or desktop computer that can access the
controller WebUI and receive streaming data from individual spectrum monitors or APs in hybrid mode. The
Spectrum Monitors window displays a list of active spectrum monitors and hybrid APs streaming data to your
client, the radio band the device is monitoring, and the date and time the SM or hybrid AP was connected to
your spectrum analysis client. This window allows you to select the spectrum monitors or hybrid APs for which
you want to view information, and release the connection between your client and any device you no longer
want to view.
 Spectrum Session Log: This tab displays activity for spectrum monitors and hybrid APs during the current
browser session, including timestamps showing when the devices were connected to and disconnected from
the client, and any changes to a hybrid APs monitored channel.
 Spectrum Dashboards: The Spectrum Dashboards window shows different user-customizable data charts for
2.4Ghz and 5 GHz spectrum monitor or hybrid AP radios. Table 125 below gives a basic description of each of
the spectrum analysis graphs that can appear on the spectrum dashboard.
NOTE: The spectrum analysis feature requires the RF Protect license. In order to convert an AP to a spectrum monitor or hybrid
AP, you must have an AP license and an RF protect license for each AP on that controller.
NOTE: For more detailed information on these graphs, see “Customizing Spectrum Analysis Graphs” on page 621
Table 125 Spectrum Analysis Graphs
Graph Title Description
Active Devices A pie chart showing the percentages and total numbers of each device type for all active
devices.
Active Devices Table This table lets you view and sort for details on each device detected on the spectrum
monitor’s radio band, including the device’s BSSID, SSID, the channels affected by that
device, and its occupied bandwidth. The active devices table for a hybrid AP only shows
active device details for devices using the hybrid AP’s monitored channel.
Active Devices Trend A line chart showing the numbers of up to five different types of Wi-Fi and non-Wi-Fi devices
seen on selected channels during a specified time interval. This chart can show devices on
multiple channels for a spectrum monitor, or the single monitored channel for a hybrid AP.
Channel Metrics This stacked bar chart shows the current relative quality, availability or utilization of selected
channels in the 2.4 GHz or 5 GHz radio bands. This chart can show multiple channels for a
spectrum monitor, or the single monitored channel for a hybrid AP.
Channel Metrics Trend A line chart showing the relative quality of selected channels in the 2.4 GHz or 5 GHz radio
bands over a specified time interval. Spectrum monitors can show channel data for multiple
channels, while a hybrid AP will show information only for its one monitored channel.
Channel Summary Table The Channel Summary table displays the number of devices found on each channel in the
spectrum monitor’s radio band, the percentage of channel utilization, and AP power and
interference levels. Spectrum monitors can show data for multiple channels, while a hybrid
AP will show a channel summary only for its one monitored channel.
