There are three time periods displayed on the page
—one second, one minute, and one hour. Each graph shows
the channel utilization and background noise level over that time period. Figure 77 shows the radio traffic on the
channel over the last 60 seconds and a calculated average percentage of utilization for the one minute period.
Figure 77 Channel Utilization (Seconds)
Figure 78 shows the radio background noise level for the last 60 seconds.
Figure 78 Background Noise (Seconds)
Figure 79 shows the Channel utilization for each minute over a one-hour period. Each minute is calculated from the
running average of the 60-second scan.
Figure 79 Channel Utilization Minutes
Figure 80 shows the running radio background average noise level for each minute over the last one hour period.
The Channel Survey page also shows two graphs (not shown here) which indicate the Percent Channel Utilization
(average readings from each minute) and the Noise Floor in one hour intervals (the graphs will only show the last
60-hour period.
