    Hi Rishi,

    This type of device is illegal in the US and probably everywhere. There is a danger that you might be jamming when someone else is trying to use their phone to call for emergency medical help. If you really want to eliminate cell phone signals the best way is with a Faraday Cage.

    Respected Mr Wiltrout

    I am making a jammer as my college project. I don't have any intentions of using this in the public. I want to keep it short ranged.......to the size of a room.

    I just have one query that, if I block the mobile signal.................will the mobile network operator company be able to know that their signal was blocked??

    Here in the UK Ofcom is very clear about the use of Jammers. http://stakeholders.ofcom.org.uk/enforcement/spectrum-enforcement/jammers/

    They do suggest alternative means, though I doubt that would constitute a college project. As John has already pointed out they are illegal in the US and likely to be in many other jurisdictions.

    If you persist in this project, you will probably get into trouble.

    Do yourself a favor and do something else.
