Are Wi-Fi networks destroying our brains? PDF Print E-mail

I just read an article explaining how a school system in Wales might bane the use of Wi-Fi networks in schools because of potential health risks. The radiation of a Wi-Fi device is extremely low, and there’s no evidence that it causes any health risks. There are many other environmental factors that pose much more harm. For example, cell phones transmit at much higher RF signal levels and are used much closer to the body as compared to Wi-Fi. As a result, cell phones offer substantially higher doses of radiation to our bodies than Wi-Fi. What do you think? Should we ban the use of Wi-Fi around children in schools?

IMHO, I'll always distance myself as far as possible from a parabolic, yagi, or any otherwise hi-gain antenna, regardless if it is connected to a 1230, 1242, or otherwise normally indoor antenna.

Since I've been working in the wireless arena for 4+ years now, I did my own research and found documented cases of high power antennas (mostly cellular or LOS, but that doesn't rule out outdoor Cisco APs) that will cause microscopic corneal damage if exposed to the signal for "too long". Too long can be just a few minutes if the signal is strong enough. It cooks you at a microscopic level.

Cisco recommends staying at least 6 inches away from the antenna for a 350 bridge, and up to 7 feet for a APs 13XX, 14XX, 15XX with high gain (22dBi) antennas.
