And now, I'm posting on behalf of 3a IT Limited...

"The channels are spread spectrun and actually use 22MHz of signal
bandwidth, so adjacent radios will need to be sperated by at least 5
channels to see zero overlap. For example, channels 1, 6 and 11 have no
overlap."[1]

This basically means that to run totally seperate wireless networks that
won't interfere with each other, you'll need to seperate the channels by at
least 5.

Also, you can put access points on different channels and as long as they
have the same ESSID and are connected to the same network, the clients
should roam freely.

Here endeth the lesson.
