Well, for one, they'd have to set up WiFi hotspots or towers everywhere, and people are already complaining about living near powerlines, cellphone towers, and I imagine the power put out by a big ass wifi hotspot would be in the same order.
I certainly wouldn't want to live near one of those towers.. or even come close to one without wearing some protection. *bjorn grabs the roll of tin foil he keeps handy to protect his future offspring*
