did they study having 50 at once Wifi signal drops off with the square of your distance from the radio. So if you feel safe sitting 5 feet from your own router, you're only getting 1/25th as much signal from your neighbor's router 25 feet away (well, almost certainly less since it's going through walls, windows, etc). (some factors can change this, like if he has a high gain directional antenna pointed directly at you, you could see more power from his router than from your own) So unless you're sitting in a Wifi router store surrounded by wifi routers, you're not getting irradiated by 50X more power even if your computer can see 50 wifi networks around you.
