Abstract
The incessant use of mobile phones can be attributed to its portability and thus have become one of the most widely used devices in mobile communication which makes it so essential in our lives. The convenience and portability of mobile phones has made it possible to be carried everywhere, e.g. Churches, lecture halls, medical centers etc. Its convenience can create inconvenience in some places when there is continuous beeping or ringtones of cell phones which becomes annoying when such noise is disruptive in areas where silence is required or the use or of mobile phone is restricted or prohibited like Libraries and Study room This paper focuses on the design of a cell phone jammer to prevent the usage of mobile communication in restricted areas without interfering with the communication channels outside its range. Interference and jamming severely disrupt the ability to communicate by decreasing the effective signal-to-noise ratio and by making parameter estimation difficult at the receiver. Interference and jamming severely disrupt our ability to communicate by decreasing the effective signal-to-noise ratio and by making parameter estimation difficult at the receiver[5] Similarly with other radio jamming techniques, mobile phone jammer sends the signal (jamming signal) of the same frequency that mobile network use. This causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable. Upon activating mobile jammers, all mobile phones will indicate "NO NETWORK”
