Figure 53 An Example Three-Channel Deployment Chapter 9 Wireless Three channels are situated in such a way as to create almost no interference with one another if used exclusively: 1, 6 and 11. When an AP broadcasts on any of these three channels, it should not interfere with neighboring APs as long as they are also limited to same trio. Figure 54 An Example Four-Channel Deployment However, some regions require the use of other channels and often use a safety scheme with the following four channels: 1, 4, 7 and 11. While they are situated sufficiently close to both each other and the three so-called "safe" channels (1,6 and 11) that interference becomes inevitable, the severity of it is dependent upon other factors: proximity to the affected AP, signal strength, activity, and so on. Finally, there is an alternative four channel scheme for ETSI, consisting of channels 1, 5, 9, 13. This offers significantly less overlap that the other one.

Figure 53
An Example Three-Channel Deployment
Three channels are situated in such a way as to create almost no interference with
one another if used exclusively: 1, 6 and 11. When an AP broadcasts on any of
these three channels, it should not interfere with neighboring APs as long as they
are also limited to same trio.
Figure 54
An Example Four-Channel Deployment
However, some regions require the use of other channels and often use a safety
scheme with the following four channels: 1, 4, 7 and 11. While they are situated
sufficiently close to both each other and the three so-called “safe” channels (1,6
and 11) that interference becomes inevitable, the severity of it is dependent upon
other factors: proximity to the affected AP, signal strength, activity, and so on.
Finally, there is an alternative four channel scheme for ETSI, consisting of
channels 1, 5, 9, 13. This offers significantly less overlap that the other one.
