Access points working in the same channel can create interference, as access points working in adjacent channels (channel number less than five apart) can also interfere with each other.
RFA delivers a warning when it detects that around a certain SonicPoint, there are more than five active APs in the channels that are less than five apart. No matter how strong their signal strength is, RFA marks the channel as highly interfered.
Highly Interfered Channels
Information about each discovered AP includes: SSID, MAC, signal strength, and channel. Two values are shown for signal strength: dBm and percentage value.
