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.

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.
