I have only one comment here. We also have to consider the advantage of these facilities. I am from a university, and I know what the advantage is of wireless networks in the universities. So I shouldn't ban it because of certain concerns, but as a person I can reduce my exposure in a way. But they shouldn't be banned.
I'll tell you one thing. Tens of thousands of people are killed every year by car accidents. Nobody complains.
This is a technology. Every technology has two sides. There is the good side and the bad side.
