Extension of the Radio Coverage Area with secondary AP in access point mode.

Use of secondary AP in access point mode with non-overlapping channels, can make your radio coverage much larger.

You can use this method only if you can connect this secondary access point to the backbone - wired part of the network. Disadvantage of this method is that the wired network has to be reachable to the second access point.

Advantage of this method is, that it is very easy to implement. It does not require much of a configuration. Only the basic configuration on second access point is needed.

If you have 2 access points – one primary and one secondary, use the non-overlapping channels. If you use two close overlapping channels, interference could occur. This leads to poor connectivity and lower bandwidth.

Make sure to have just right distance between two access points. If they are to close, you can have congestion, and radio coverage area will be smaller.

The most important thing in the big wireless LAN networks is to assign the right channels on the access points. This will minimize the overlap of signals. Access points within a range need to be configured with non-overlapping channels (i.e., 1, 6 and 11).
