The NZ Herald is reporting that there is growing concerns in NZ over the use of wifi in NZ (like in britian) over the use of wireless networks in schools to deliver broadband and network resources to the students

I ask if a school were to say 'right, no more wifi' and they switch off their access points, would that not do anything to help.
Wouldnt there still be the same or increasing amounts of students and teachers in the classrooms / school grounds who are using laptops? I would expect that all of these laptops have the wifi turned on by default and most people wouldnt know how to turn it off. If so then wouldnt there be much the same amount of these so called radio waves of concern in the air?

I remember in high school before wifi was introduced that probably 100 students used laptops and we, one day found out we could network with each other in different classrooms of the same building when a couple of us came close enough together.
Even before then many had the wifi on by default not knowing it, and the lack of access points didnt stop us from using the laptops at school.
