Channel
Management
Without automated channel management, channel assignments to
clustered access points might be made on consecutive channels, which
would overlap and cause interference. For example, access point1 could
be assigned to channel 6, access point2 to channel 6, and access point3
to channel 5 as shown in Figure 25.
.

With automated channel management, access points in the cluster are
automatically reassigned to noninterfering channels as shown in Figure
26.
