More on Wi-Fi health risks and measuremen
The agerage WiFi access point emits 200 mV. The average wirelessYou are talking about the new 802.11ac standard, which was approved in January 2014. It is being marketed to schools. I just did some quick research and discovered that access points under this standard can emit up to 700 mW in the 2.4 GHz band and 1000 mW in the 5 GHz band. Quite a bit more powerful than previous devices. However, one such device can cover 10,000 square feet, so there will be fewer of them, and the exposure to the average student will be less. Of course, those classrooms that are next to such a device will be very heavily irradiated.
computer emits 200 mV. If there are 100 computers in use, then
obviously the total radiation is 100 times stronger than if there is 1
computer in use. Also, a school has a number of access points, while a
home usually has only 1.
You won't. It all depends on the transmitters used. Is there one for each classroom or is there one for the school? Then are you measuring close to the transmitter or at some distance. Where is the nearest head with respect to the transmitter? What is the field at the nearest head, that is what is important. Is the Wi-Fi at either location switched on all the time, or only as required?
Some homes will have higher fields than some schools and some will be the reverse.
This is much too complicated a subject to cover with an overall answer.
A noteworthy point for all exposures, from his general statement found here http://rfemf.com/counter.
- The Fallacy of Spatial Averaging: power density drops by the square of the distance from the antenna, but the actual power of any single stream of pulses does not significantly drop over the first 50 feet.What I think this means is that if one is in the way of a beam within 50 feet of the source, each individual stream of radiation is still nearly as strong as at the source, the power density decreases because, like a light beam, the individual streams fan our, so you don't get exposed to so many streams per sq inch of tissue. But one has to wonder, what about the small area of our bodies that are being continually bombarded.

the 100 number is a comparison between low end in home with high end in a school
I would always contextualize the number
here is the peyman dosimetry study in schools (they site a high of 2 mcw/cm^2 and .02 is the lower end of home Wi-Fi
also- look for ray pealer's you tube videos- I think he is trackingcandles-- shows difference between Wi-Fi in school and parking lot of a cell tower
