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 3 channels, it should not interfere with

neighboring APs as long as they are also limited to same trio.

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.

Load Balancing

Because there is a hard upper limit on an AP’s wireless bandwidth, load balancing can be crucial in

areas crowded with wireless users. Rather than let every user connect and subsequently dilute the
