While being on the same channel as another network is not ideal, is it better than being on a neighboring overlapping channel because 802.11 specification has methods for dealing with co-channel interference?
Or in other way, is it better to be in the non overlapping channels 1, 6, and 11 (besides they will be probably shared between many other networks) or choose some channel between them containing less networks?
I am asking about the 2.4GHz ISM band.
