Wi-Fi Wonderer asks: "I've been wondering what the difference is between the different regions that can be set on a Wi-Fi router? I know the region determines which channels are available, but I can't find any concrete information on anything else. Do regional settings also determine power output, bandwidth, and/or encryption mechanisms? If you are in a Wi-Fi dense area does it make sense (legal ramifications aside) to choose a different regional setting so as to avoid interference? Will one region give a greater broadcast range than another? Is there any documented information on exactly what configuration settings go with each region?"
