Wi-Fi interferers and Adjacent Channel Interference (ACI).
For additional information on how the spectrum analysis feature measures ACI, see Channel Metrics on page 794.
This graph can show data recorded for the last ten, thirty, or sixty minutes. 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. When you hover your mouse over any line in the chart, a tooltip shows the
percentage of the channel being utilized at the specified time. The example in Figure 125 shows that channel 1
was 70% used at the selected time in the chart.
Figure 125 Channel Utilization Trend
Table 161 describes the parameters you can use to customize the Channel Utilization Trend chart. Click the
down arrow in the upper right corner of this chart, then click the Options menu to access these 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.
