Blocking mobile reception....
Is there a readily available material that could be used to block mobile phone signals? I know, lead! I mean some sort of practical shielding that could be put up in cinemas etc to stop phones going off? If so why don't the cinimas etc use it? It would also help in snooker matches etc. Obvious BGB chances here!

The cheapest way to do this is to jam the signal by transmitting noise on the frequencies used by the phones at a higher power than the signal that is in the air.
However as those frequencies are regulated I don't believe it is legal to do this unless you have a license - which is probably why it isn't done at the moment.
Most metals are good at blocking microwaves but you need comprehensive covering as those waves are persistant little so and so's and I guess the cost is just too much.

Apart from the fact that you can get banged up for up to two years for using any device to block mobile phone signals in the UK.
