Figure 120 Active Devices Trend Graph
An Active Devices Trend chart created by a hybrid AP displays data for the single channel monitored by that
device. For spectrum monitors, the Active Devices Trend chart can display values for up to five different
channels and device types. These graphs show the following data by default:
l For SMs on the 2.4 GHz radio band, Wi-Fi APs on channel 1, 6, and 11.
l For SMs on the 5 GHz band, Wi-Fi APs on channel 36, 40, and 44.
Table 156 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
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. For spectrum monitors using the 5
GHz radio band, click the Channel Numbering drop-down list and select either 20
MHz or 40 MHz channel numbering to identify a channel numbering scheme for
the graph. Graphs for AP radios that support 802.11ac include an additional
80MHz option for very-high-throughput channels.
