Channel Assignment
It is also possible to implement a dual-band deployment scheme, as shown in
. The top left
portion of the diagram shows the 802.11b/g-only deployment, which uses the three nonoverlapping
channels (channels 1, 6, and 11) to map out a pattern that has the least co-channel interference; that is,
interference from an AP close by that is on the same channel, that is operating at sufficient power levels
with its coverage pattern overlapping with that of another access point. It also shows an 802.11a
deployment, which uses the eight nonoverlapping channels. The right side of the diagram illustrates how
the channels would be mapped in a dual-band deployment.
