18.6 “Air Utilization” test
To capture spectrum heavy-users and misconfigurations – such as extensive use of legacy

To run the test:
1. Select antennas, at least one must be selected.
2. Select the desired channels with the check-boxes.

detailed result if “Show graph” is selected for the activated row:
