For example, looking at

Multiple Channel Configuration (page 140)

, to set up

a three channel system you could configure the Access Points RLMs as
follows:

•

All Access Points RLMs identified as operating on channel A would use
channel 1 (2412 MHz)

•

All Access Points RLMs identified as operating on channel B would use
channel 6 (2437 MHz),

•

All Access Points RLMs identified as operating on channel C would use
channel 11 (2462 MHz)

This would just meet the minimum channel separation of 25 MHz for
neighboring Radio Link Modules that is recommended for optimal operation.

A station roaming from location

X to location Y would automatically switch

its radio consecutively from channel A, B to C to remain connected to the
network.

When your network includes RLM devices, you can use the RLM in
combination with two PC Cards CP 1515 to create overlapping cells for
maximum throughput performance.

In that case, you must assign different frequency channels to each card (with
a separation of 25 MHz or more) to avoid cross-talk between the two cards.

To change the frequency of your Access Point RLM, proceed as follows:

Connect to the RLM by opening the RLM Manager, selecting the target
Access Point RLM, and click the
