Utilization
Utilization (also called Duty Cycle in some applications) is a relative score that helps
determine how usable a channel is. It measures the percentage of time a signal was at or
above the Utilization Threshold. This threshold can be adjusted in the top left corner of the
Utilization tab. The selected time span in the waterfall navigation is used in the Utilization
calculation.
Channels Table
Current – The current represents an average of the most recent amplitude readings within
the channel range.
Grade – This calculation uses the entire 20 Mhz width of a Wi-Fi channel. Higher power
levels near the center of the channel will affect the grade more negatively. A high grade of
90 or above can be interpreted as an “A” while 80 or above is a “B.” Anything below 70 is not
recommended for Wi-Fi deployment.
Average - For each channel range (for example, Wi-Fi Channel 1, 2401 - 2423 MHz),
Chanalyzer calculates the average power within that channel frequency range.
Max - This is the highest amplitude point within the Wi-Fi channel frequency range.
Utilization – The percentage of all noise above a defined amplitude threshold. The default
amplitude is -85dBm.
Networks – Once network scanning is initialized, Chanalyzer will list the networks that are
detected.
