Multiple Channel Configuration
The stations are capable of switching their operating frequency channel
dynamically when roaming between Base Stations that have been configured to
use different radio channels.
Using different channels enables you to optimize wireless performance,
assigning different frequency channels to neighboring Base Stations. Multiple
frequency configurations may prove very useful in environments where:
! A high concentration of wireless stations are operational.
! The stations experience a performance decrease in terms of network
response times as a result of the collision avoidance protocol (for more
information, see RTS/CTS Medium Reservation on page 6-11.
Figure 2-4: Dual Channel Configuration
! By configuring neighboring Base Stations with different frequencies, you
create separate mediums for each wireless cell. Operating at different
channels, the stations can no longer “hear” one another, and therefore no
longer need to defer communications.
! When the configuration pictured in Figure 2-4 represents a single channel
system, both station 1 and station 2 share the same medium. Station 1
might need to defer communication with the Base Station when it senses
that station 2 is already communicating with the Base Station in the
neighboring cell.
As is the case in any roaming environment, you must configure all Base Stations
in multiple channel configurations with an identical network name.
