I think it's already started.
I nearly started a fight at a party by suggesting the best place to put a GSM base station is very close to, or maybe within the school grounds.
If you understand the science, then it makes sense. If you don't then you hit out at the suggester (and miss).
Happy to explain how this works here or via PM.

The science is simple... The Antennas used only transmit from the side (note: The Antennas I refer to are inside the protective casings we see mounted on the Mobile base stations). As such, they are oriented so that they transmit out of the side of the base station, where the signal will reach the most users, rather than downward, where the only thing receiving the signal will be the earth and a couple of people standing by the base station.
To ensure that the signal reaches the maximum amount of people possible, the base station is normally mounted quite high, as gravity does (slowly) affect the path taken by radio signals.
As such, by putting the mobile mast next to the school, the signals it generates will be flying several metres over everyone's head.
TV and radio transmitters also suffer the same limitations, but they have to transmit over a wider area, hence they can be hundreds of feet tall (600 odd in the case of Crystal Palace).
That's a gross simplification, but I believe I've explained the basics quite well.
