  • Hello everyone, I need to buy a cell phone jammer in the classroom. As a teacher, I really can not stand the students have been ignoring me, has been staring at the cellphone.
    So, what kind of jammer do I need to choose?
  • If you want to jammer cell phone signals for students, then I suggest you use a jammer that can blocker 2G 3G 4G signals. Basically interfere with the above signals, the students can only see the blackboard.
  • Hello alexy!
    Given your situation, the jammer that suits you needs to meet the following two points:
    1. Can blocker GSM / CDMA, 3G, 4G and other cell phone signals
    2. At least jammer range 15-20 meters, to ensure that cover the entire area of the classroom
    You can choose the jammer according to the above criteria. Hopefully my answer is of help to you

Howdy, Stranger!
