Cell Phone jammers are illegal in most of the world. Is this what you are essentially trying to build?

Chicken wire all around the room?
Are you a teacher, trying to stop cheating in exams, by any chance?

yea cell phone jammers, and there is no rule talk about them in my country so it is allowed

no i am not a teacher but i would love to know and help my teacher about that, like a last year project

Cell phones use a number of different frequencies. It could be a better idea to detect that a phone is being used; they all make that burbling noise when near amplifiers etc., so you could lay wires all around the room.

Since it is illegal to jam radio transmissions in most parts of the world, this thread is now closed.
