Table 208 describes the other values that can be displayed in the Active Devices Trend chart. Click the down arrow in the upper right corner of this chart then click the Options menu to access the Active Devices Trend configuration settings. Once you have configured the desired parameters, click OK at the bottom of the Options menu to save your settings and return to the spectrum dashboards.

Parameter	Description
Band	Radio band displayed in this graph (2.4 GHz or 5 GHz).
Show Trend for Last	Amount of elapsed time for which this chart should display data.
Channel Numbering	For spectrum monitors using the 5 GHz radio band, select either 20 MHz or 40 MHz channel
	numbering to identify a channel numbering scheme for the graph.
	NOTE: This parameter is not configurable for graphs created by hybrid APs or spectrum
	monitor radios that use the 2.4 GHz radio band. A hybrid AP on a 20 MHz channel sees 40 MHz
	Wi-Fi data as non-Wi-Fi data.
Show lines for these	The Active Devices Trend chart can display values for up to five different device types on
channels	different channels for a spectrum monitor, or a single device type for a hybrid AP.
	To choose which type of data each line should represent, click the channel number drop-down
	list and select a channel within the radio band, then click the device type drop-down list and
	select one of the following device types.
	•	WiFi (AP)
	•	Microwave (This option is only available for 2.4 GHz radios)
	•	Bluetooth (This option is only available for 2.4 GHz radios)

Channel Metrics

This stacked bar chart can show one of three different types of channel metrics; channel utilization, channel availability, or channel quality.

By default, this chart displays channel utilization data, showing both the percentage of each monitored 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).

NOTE: ACI refers to the interference on a channel created by a transmitter operating in an adjacent channel. A transmitter on a nonadjacent or partially overlapping channel may also cause interference, depending on the transmit power of the interfering transmitter and/or the distance between the devices. In general, ACI may be caused by a Wi-Fi transmitter or a non-Wi-Fi interferer. However, whenever the term ACI appears in Spectrum Analysis graphs, it refers to the ACI caused by Wi-Fi transmitters. The channel utilization option in the Channel Metrics Chart shows the percentage of the channel utilization due to both ACI and non-Wi-
