Novel Design for Mobile Phone Jammer

Abstract

The goal of the project is to design a mobile phone jammer which is cheap and compact. Multiple utilities that the project offers, include, maintaining mobile phone silence in libraries, mosques, and offices. It can also help to avoid unfair means via use of mobile phones in exam halls. The project also offers prevention against IEDs in conflict zones. The project makes use of a noise generator whose output is fed to several VCOs, operating on different frequencies being used by mobile phones. Using multiple antennas the noise signal modulated with GSM, DCS, CDMA and 3G frequencies, respectively, are transmitted to do the desired jamming. To avoid overheating, a heat sink, along with cooling fans, is used for operating the jammer for longer durations. Its compact size and light weight help in its easy operation and quick mobility. The project will be a great deal for several organizations including educational institutes, security organizations and especially law enforcement agencies.
