One word to defeat the paint idea.
Seems like we have another case of a non technical issue with people looking for a technical solution (because everyone knows IT guys can do anything ).
The issue is students are using their phones - this is a discipline issue and should be treated as such.
even blocking signals wouldnt stop kids using them as cameras which is possibly as bad if not worse anyway
Good luck with this one.
One thing to remember is the frequency bands which will be used for 4g are going up for auction soon. Will any solution you buy now be able to block them?
Illegal to block, Faraday cage would work but block everything (and is impractical).
How about a detector and a member of SMT doing spot checks in a corridor; like a speed trap? After a few weeks of
crushed phonesdetentions/letters home etc the message would get through. Maybe you could get several schools to club together to buy the detector?
We caught a little scrote with the mark scheme for his mock exam open on his phone just last week...

I think mobile phone detectors would be the best option, at least then the students actually get caught and can be reprimanded. showing that you are looking for people with phones in school. not just for people using them in lessons
When I looked into mobile phone detectors a couple of years ago, they would only detect a phone while it was communicating with its mast, which only happens every now and again or while a call is being made.
In addition to this they would only tell you that there was a phone switched on in range of the detector they could not tell you the location of the phone.
anybody know if this has changed?
The thing is, parents now insist on their children having mobile phones on their person, 'in case of emergency'. Also, in today's age of smartphones, a lot of mobiles are communicating without the conscious action of their owner. Things like facebook checking for new messages/posts/tags/etc, apps checking for upgrades, heck even the operating system checking for newer versions, or Android querying any new mail in your Google inbox.
Will you be able to differentiate between behind-the-scenes, uncontrollable activity and user-initiated activity? Or are you just going to enforce an 'All phones must be switched off at all times' rule, in which case you'll get "Well what if I need to get a hold of my son/daughter!?" (because apparently phoning the school office and asking for them just isn't good enough.)

I really don't see this is possible and the costs to try and prevent it are going to be huge. Even then, it won't be water tight and it would create problems for staff and your WLAN.
