See: > It was my understanding that the regulatory domain embedded in the card firmware was used only to disable some channels completely, on the basis of the fact that the radio/antenna hardware could have been untested on those. I don't understand (from a compliance point of view) why it can force some channels to passive scanning: since this is purely a matter of which nation the card is operating in, shouldn't it be managed only by CRDA?
