Discussion Overview

The discussion revolves around the feasibility of building a device that can cut or stop mobile signals within a range of 5-10 meters. Participants explore the technical aspects, materials needed, and legal implications of such a device.

Discussion Character

  • Debate/contested, Technical explanation

Main Points Raised

  • One participant inquires about the possibility of constructing a signal-cutting device, seeking information on circuits and materials.
  • Another participant points out the legality of cell phone jammers, suggesting that the original inquiry may be about building such a device.
  • A different participant humorously suggests using chicken wire, questioning whether the intent is to prevent cheating in exams.
  • One participant clarifies that they are not a teacher but are interested in helping with a project related to this topic.
  • Another participant proposes an alternative approach of detecting phone usage through sound interference rather than jamming signals.
  • A later reply emphasizes the legal restrictions surrounding jamming devices, stating that the thread is now closed.

Areas of Agreement / Disagreement

Participants express differing views on the legality and feasibility of building a signal-cutting device, with no consensus reached on the technical aspects or the appropriateness of the project.

Contextual Notes

Legal implications of building such devices vary by region, and the discussion does not resolve the technical challenges or requirements for constructing the device.

Hi,

If i want to build a device that is able to cut or stop the signal of the mobile just of 5-10 meters

is it possible? , and if it is what is the circuit, and what is the materials that i need?

And this is not a Homework,,i am sorry for my mistake before.

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.

I know , but i prefer to build an device
 
Since it is illegal to jam radio transmissions in most parts of the world, this thread is now closed.
