Chapter 8: Channel Management

Configuring Advanced Settings (Customizing/Scheduling Channel Plans)

80 Psion Teklogix 9160 G2 Wireless Gateway User Manual

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.

Table 8.3 Advanced Settings

Field Description

Advanced

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

Change channels if interfer-

ence 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.

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.

Determine if there is better set

of channel settings every__

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).

Use these channels when

applying channel assignments

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.
