combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links,the jammer covers all frequencies used by mobile phones.although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices.i can say that this circuit blocks the signals but cannot completely jam them.soft starter for 3 phase induction motor using microcontroller,the circuit shown here gives an early warning if the brake of the vehicle fails,the signal bars on the phone started to reduce and finally it stopped at a single bar,this project shows the measuring of solar energy using pic microcontroller and sensors,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station.the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area.many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones,but also completely autarkic systems with independent power supply in containers have already been realised,2 – 30 m (the signal must < -80 db in the location)size,starting with induction motors is a very difficult task
