The usage of cell phones has increased enormously; at present silence and security is the need of the hour in many
places. This can be done by using cell phone jammer, which blocks all the signals. This paper describes the design of
an enhanced technique for jamming the cell phone signals. Our main objective is to concentrate on a specific band of
frequency, which makes communication possible, by jamming this frequency we block out the specific signal that are
responsible for making the call. This method enables the jammer to be more precise and effective, so precise that it can
focus on specific area and allowing the programmer to define the area. The major advancement will be that emergency
services can be availed which is very crucial in case of any calamity, they are intelligent devices as they act only after
they receive signals and also it has a lesser power consumption than existing models. This technique has infinite
potentials and sure can this be modified to match all our imaginations.
