Back-up of the Configuration).
Frequency Channel Management
When your network consists of more than one Base Station, we recommend
that you alternate sub-channel frequencies between adjacent Base Stations to
provide more bandwidth to the wireless stations in each cell.
The number of available channels is subject to local radio regulations that apply
in your country. A list of supported channels for your country can be found in
the online documentation of the Wireless Client Adapter.
Dual Channel Configuration
A Dual Channel system could look as follows:
! All Base Stations identified as operating on channel A would use channel 1
(2412 MHz).
! All Base Stations identified as operating on channel B would use channel 11
(2462 MHz).
Figure 6-27: Dual Channel Configuration
This way you can apply a maximum channel separation for neighboring Base
Stations that will easily satisfy the requirements recommended for optimal
operation.
Station 1 would use channel A to communicate with its Base Station without
bothering station 2 to defer its transmissions to the neighboring Base Station.
When either one of the stations would roam to another location, it will
automatically switch its radio to any other operating channel required to remain
connected to the network.
