Proposed Channel Assignments Table

The Proposed Channel Assignments table shows the proposed channels that are
to be assigned to each WAP device when the next update occurs. Locked
channels are not reassigned—the optimization of channel distribution among
devices takes into account that locked devices must remain on their current
channels. WAP devices that are not locked may be assigned to different channels
than they were previously using, depending on the results of the plan.
For each WAP device in the Single Point Setup, the Proposed Channel
Assignments table shows the location, IP Address, and Wireless Radio, as in the
Current Channel Assignations table. It also shows the Proposed Channel, which is
the radio channel to which this WAP device would be reassigned if the channel
plan is applied.
Configuring Advanced Settings
The Advanced settings area enables you to customize and schedule the channel
plan for the Single Point Setup.
By default, channels are automatically reassigned once every hour, but only if
interference can be reduced by 25 percent or more. Channels are reassigned
even if the network is busy. The default settings are designed to satisfy most
scenarios where you would need to implement channel management.
You can change the Advanced settings to configure the following settings:
•Change channels if interference is reduced by at least—The minimum
percentage of interference reduction a proposed plan must achieve in
order to be applied. The default is 75 percent. Use the drop-down menu to
choose percentages ranging from 5 percent to 75 percent. Using this
setting lets you set a threshold gain in efficiency for channel reassignment
so that the network is not continually disrupted for minimal gains in
efficiency.
For example, if channel interference must be reduced by 75 percent and
the proposed channel assignments will only reduce interference by 30
percent, then channels will not be reassigned. However, if you reset the
minimal channel interference benefit to 25 percent and click Save, the
proposed channel plan will be implemented and channels will be
reassigned as needed.
