Forum :: Lounge :: Tell me more about a jammer device

Does anyone know anything about mobile  jammers?  I'd like to get one for my classroom.  Kids are nor supposed to use cell phones in the building (landline phones are in every room in case of emergency).  The kids still sneak phones in and try calling or texting on the sly. I've got a website  from Google for help.Has anyone buy a one from it? Has anybody worked with these? I need more details.Am i doing the right thing then?
Introduce some more details about it!

Jammer devices just block certain frequencies that cell phones use for communications. They do work though, my physics teacher many years ago had one that worked really well
