Wi-Fi Routers - The Differences for Each Region?

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?"

if you're in the UK and expecting US visitors to your wireless network you would be well advised to avoid using channels 12-14 since US wifi cards won't see your wireless router
