Ideally, it would attempt to get co-channel with other APs on the same =
channel.

Especially in 2.4GHz (or any of the 5GHz bands).

Because you would *much* rather share the air (via collision avoidance) =

And, given that everyone has a DC receiver these days, there are NO =
=93non-overlapping channels=94.
