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 on 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.
A Pass, Warning, or Fail icon is also displayed for
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.
A Pass, Warning, or Fail icon is also displayed for
each channel.
Once the Air Quality test completes, select the blue triangle
icon next to a channel under Co-Channel Interference or
Adjacent Channel Interference to open a list of the APs
interfering on that channel.
Then, you can select the down
arrow next to each interfering AP to view its BSSID, SSID, and
Signal strength.
Rogue Access Points Test
This feature classifies Rogue Access Points based on the user-
selected Authorization status of the detected APs. Rogue
Access Point tests as a whole can be included or excluded
from AutoTest by accessing the AutoTest Settings screen.
Figure 23. Rogue Access Points Test
• If no rogue access points are detected, the field turns
green.
• If AirCheck G2 detects APs that have a Fl
agged status,
the field turns yellow.
