Parameter Description
To choose which type of data each line should represent on a chart for a
spectrum monitor, click the channel number drop-down list and select a
channel within the radio band, then click the second drop-down list and select
either Channel Quality, or Channel Availability.
Select the checkbox beside each channel entry to show that information on the
chart, or deselect the checkbox to hide that information.
Channel Summary Table
The channel summary table provides a summarized or aggregated view of key statistics. Spectrum monitors
display spectrum analysis data seen on all channels in the selected band, and hybrid APs display data from the
one channel they are monitoring. The example in Figure 123 below shows that a spectrum monitor sees 44
Valid APs and 52% channel utilization on channel 40 in the 5GHz radio band.
Figure 123 Channel Summary Table
Spectrum monitor radios using the 5 GHz radio band can display channels using either 20 MHz or 40 MHz
channel numbering. Spectrum monitor radios that support 802.11ac can also display 80MHz channels. To
toggle between these channel numbering modes, click the down arrow in the upper right corner of the graph
titlebar, then click either Show 20 MHz Channels, Show 40 MHz Channels or Show 80 MHz Channels.
Click any of the column headings to sort the information in the table by that column criteria. Make a column
wider or narrower by clicking the border of a column heading and dragging the border to a new position.
Table 159 describes the output of the Channel Summary table.
