Channel View Graph Measurements
Channel Utilization Graph
The Channel Utilization graph indicates the channel utilization and number of APs detected on each channel in a bar graph
format.
Channel Utilization measures the percentage of time that the RF channel is detected as “busy” and that the radio could not
initiate communication due to RF channel interference. The channel could be detected as “busy” because of WiFi transmissions
by APs on the channel or non-WiFi interference on the same frequency as the channel under test.
The x-axis displays the channel number, the y-axis displays utilization (in %). The number included in each bar graph displays
the number of APs detected on each channel.
For each selected channel, additional information is displayed at the top of the graph.
A dotted line indicates the utilization threshold as configured in the Setup menu (see
Channel View Measurements
The following measurements are displayed in the Channel View Table results and Details window. Results are updated every
second while the network scan is running. All channels in the 2.4 GHz and 5 GHz frequency bands are scanned.
Channel #:
Channel number in the 2.4 GHz and 5 GHz frequency bands.
# of APs:
Number of Access Points/SSID detected on the channel.
Best Signal:
Strength in dBm of the strongest signal of the APs located on the channel. Displays “N/A” if no AP is located
on the channel.
