Bomb jamming | Can I use cell phone signal blocker for schools?

Hello James! The question of using or not using cell phone jammers in schools is disputed a lot by many authorities and among people too. In some countries and US states they are forbidden to use, and in others they are legal, but the laws and allowances are changing often. We have a great desktop model of cell phone signal blocker for schools which you can use in your classroom. It can block most commonly used frequencies of wireless communications. While it may be not totally legal in the region you live, at least you will be sure that your pupils cannot cheat at exams and will listen to you without distracting to their mobile phones.
