7.2.4 AP Interference View
This view displays the level of 802.11 channel interference at various locations on the plan. The interference is based on the
signal strength of different APs, operating on the same channel, at that location. This view helps you plan for minimum
interference to provide better network connectivity and better throughput for higher end user satisfaction.
There are Interference View checkboxes at the bottom of the AP Interference View screen.
• Co Channel: Select to show interference due to channels with the same frequency
• Adjacent Channel: Select to show interference due to adjacent channels
• Select both the checkboxes to view the total channel interference due to both Co-Channel and Adjacent Channel
channels.
The color palette displays six levels of interference: Negligible, Very Low, Low, Moderate, High, and Very High.
The Network Utilization drop-down list at the bottom right corner of the screen allows you to choose Low, Medium, or High
level of network utilization with which channel interference is to be computed. Network Utilization is a measure of the
amount of 802.11 activity that is the traffic generated due to communication between 802.11 devices in the network. It also
depends upon the channel of the communicating devices. Communication on a channel adds load to itself and to adjacent
channels (in case of 802.11b and 802.11g) due to overlap in frequency spectrum of adjacent channels.
Click <Select Channels> at the bottom right corner to view the panel of channels operating on various protocols. You can
select the channels in this panel. All the channels that are not selected, do not contribute to the interference. For example, if
you do not select channel 6 and there is a device on the layout operating on channel 6, Planner does not consider this device
for calculating interference.
You can also view the channel interference for certain channels by going to ToolsSettingsPreferencesAP Views.
