A simple zero-hassle solutions is to have walls that block any cellular and wifi signals. It solves the problems you mention.
I don't know why such walls are not more common in schools too. A lot of parents would be happy to pay for such walls if the learning experience improves substantially.
Edit: about the emergency and possible bomber attack: if the block-signal-mecanism is active (create some sort of interference) then it becomes easy to deactivate the mechanism automatically when the fire alarm or other emergency is triggered: simy cut the power source.
- dannyw 9y agoJamming legal signals, even in private property, is very very illegal.
- jknz 9y agoSome big companies in Europe have such walls for their headquarters, probably for productivity. I guess that their solution is fairly legal, although it may not involve jamming.
- DrScump 9y agoJamming, yes. If your venue just happens to block all signals as an effect of its design (working like a Faraday cage), it could legally have repeaters that are powered off during the performance proper.
- tinus_hn 9y agoThat requires the largest hole in the cage to be smaller than the signal wavelength, which makes it pretty difficult to get in.
