The mobile jammer is used to block the signals between the mobile phone and the base station. This can be done by generating some kind of hurdles for the range of frequency of signals. It will generate very low or no signals for the user. It has many applications like; for defense use, in educational institutes, and in offices during meetings. I have designed this mobile jammer for defense use. In military areas, they use mobile jammers to limit communication during hostage, bomb threats conditions, and military operations.

The benefit of using these jammers is to make secure everyone from any worst situation. Because in these cases the use of the mobile phone can be a source of communication between terrorists or opponents. I have designed the PCB board of mobile jammer that is very flexible to use as it is portable can be carried in the pocket by providing a user-friendly interface. Moreover, a proteus simulation of the design is also available to test its work. In the end, I have uploaded all the design files on the Inventhub for the manufacturer and the user.
