In my experience, it's a setting in the access point configuration.
So, it's either one or the other. Isn't this a regulatory issue, country specific?
That affects what channels are available, not how they're used. WiFi is an unlicenced service that has no protection from interference, so you can do whatever you want, so long as you comply with the regs, WRT frequencies used, power etc. Also, some of the WiFi channels are shared with other services, which are protected from interference. For example, the lower part of the 2.4 GHz band partially overlaps an amateur radio band. In that range, amateur radio has priority and protection from interference caused by WiFi and other unlicenced uses. Parts of the 5 GHz band are used for navigation and other uses that are protected from WiFi.
Hum. Users are not aware of that at all. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" (Minas Tirith))
