Figure 17. Air Quality Co-Channel and Adjacent Channel
Interference Results
Using AutoTest to Diagnose Your Network Health
Co-Channel Interference
The Co-Channel Interference results display the top three
channels in each band (2.4 GHz and 5 GHz) with the highest
number of APs that exceed the minimum AP signal level
threshold in the same channel.
This measurement is independent of SSIDs and solely looks
at the number of APs using the same channel and their signal
quality. It accounts for 40-MHz and 80-MHz channels in the
5-GHz band by counting an AP on its primary and each
secondary channel.

Warning, or
each channel.
Adjacent Channel Interference
The Adjacent Channel Interference results display the top
three channels in the 2.4-GHz band in which APs may
experience Adjacent Channel Interference. For each channel
on which at least one AP is found, the Tester counts how
many APs are operating on other channels that overlap with
that channel. It accounts for 20-MHz and 40-MHz channels in
the 2.4-GHz band. The Adjacent Channel Interference
measurement does not apply to the 5-GHz band.
