Analysis of Jammer Circuit

Abstract — Users of mobile communication devices have dramatically increased in the last twodecade. This proliferated the need of a more effective and secures signal scrambler for a cultured society. Mobile jammer circuits are used to prevent mobile phones from receiving or transmitting signals. Mobile jammer effectively disables mobile phones within the defined range zones without causing any disturbance/interference to other communication means. Mobile jammer can be used in any practically location, but generally are used in places where phone calls are disruptive like Schools, Churches, Libraries, Hospitals etc. Similarly with other radio jamming, mobile jammer sends the radio waves of same frequency that mobile phones uses to block the signal. This signalcauses interference with the communication between mobile phones and base stations to make the phones unusable. When mobile jammer is activated all mobile within the range willindicate "NO NETWORK ” service. Design and study of Mobile jammer is discussed in this pape
