Authorized APs placed on a floor map can interfere with each other if they operate on overlapping channels. Authorized APs can receive interference from other APs in the neighborhood (external APs) that operate on channels overlapping with the channels of the authorized APs.
You can review the channel allocation of authorized APs placed on the floor map with the InterferenceView. APs interfering with one another can be placed in different locations or channels on which they operate can be changed to avoid interference with one another. This view can be overlaid on any other view available on the floor map, such as AP coverage, Sensor coverage, AP Link Speed, or AP Channel Coverage.
Interference between APs on the floor map is indicated with a red line.
You can change the signal strength on the slider and view the interference between APs on the floor map based on the signal strength.
Each AP has four colored circles above it in the Interference View. The numbers in the circles indicate:
- The number of neighboring external APs that interfere with the AP on the floor map. The external APs can interfere on the 2.4 GHz and 5 GHz frequencies.
- The client associations with the AP on the 2.4 GHz and 5 GHz frequencies. The information is useful if the AP channel is to be changed to prevent interference with other authorized APs on the floor map.
To display the Interference View:
- Select Locations.
- Click the icon.
- Select the 5 GHz or 2.4 GHz check box.
- You can adjust the Signal Strength slider above the Interference Legend to view the interference based on the signal strength.
