There are only 3 non-overlapping channels available in the
802.11b standard.These are Channels 1,6, and 11. For WiFi access
points that are located near each other it is recommended that they
each use one of the above non-overlapping channels to minimize the
effects of interference.

This overlapping of 2.4GHz channels are better visualized from the chart below.
