Chapter 6: Channel Management

Change channels if interference is reduced by at least

Specify the minimum percentage of interference reduction a proposed

plan must achieve in order to be applied. The default is 25 percent.

Choose percentages ranging from 25 percent to 75 percent from the

list.

This setting lets you set a gating factor 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 are not reassigned. However; if you re-

set the minimal channel interference benefit to 25 percent and click

Update, the proposed channel plan will be implemented and channels

reassigned as needed.

Determine if there is better set of channels every

Select the schedule from the list. The range of intervals is from 1

Minute to 6 Months, and the default is 1 Hour (channel usage

reassessed and the resulting channel plan applied every hour).

Use these channels when applying channel assignments

Choose a set of noninterfering 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 classical 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.

Apply channel modifications even when the network is busy

Click to enable or disable this setting.

A checkmark indicates it is enabled and channel modifications are

applied even when the network is busy.

If this is not checked, channel modifications are not applied on a busy

network.

This setting (along with the interference reduction setting) is designed

to help weigh the cost/benefit impact on network performance of re-

assigning channels against the inherent disruption it can cause to

clients during a busy time.
