Chapter 8: Channel Management
Configuring Advanced Settings (Customizing/Scheduling Channel Plans)
These defaults are designed to satisfy most scenarios where you would need to implement
channel management.
You can use Advanced Settings to modify the interference reduction potential that triggers
channel re-assignment, change the schedule for automatic updates, and re-configure the
channel set used for assignments.

Description
Click the "Advanced" toggle to show / hide display settings that modify timing and details of
the channel planning algorithm. By default, these settings are hidden.
Specify the minimum percentage of interference reduction a proposed plan must achieve in
order to be applied. The default is 25 percent.
Use the drop-down menu to choose percentages ranging from 25% to 75%.
This setting lets you set a gating factor for channel re-assignment so that the network is not
continually disrupted for minimal gains in efficiency.
For example, if channel interference must be reduced by 75%, and the proposed channel
assignments will only reduce interference by 30%, then channels will not be re-assigned.
However; if you re-set the minimal channel interference benefit to 25% and click Update,
the proposed channel plan will be implemented and channels re-assigned as needed.
Use the drop-down menu to specify the schedule for automated updates.
A range of intervals is provided, from "1 Minute" to "6 Months". The default is "1 Hour"
(channel usage re-assessed and the resulting channel plan applied every hour).
Choose a set of non-interfering channels on a particular band ("b/g" or "a"). The choices are:
• b/g channels 1-6-11
• b/g channels 1-4-8-11
• a
IEEE
802.11b/802.11g
modes (802.11 b/g) support use of channels 1 through 11. For the
"b/g" radio band, the classic set of non-interfering channels is 1, 6, 11.
Channels 1, 4, 8, 11 produce minimal overlap.
IEEE
802.11a
mode supports a larger set of non-consecutive channels (36, 40, 44, 48, 52,
56, 60, 64, 149, 153, 157, 161, 165). All "a" band channels are non-interfering.
