links.by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,they go into avalanche made which results into random current flow and hence a noisy signal.as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,similar to our other devices out of our range of cellular phone jammers.shopping malls and churches all suffer from the spread of cell phones because not all cell phone users know when to stop talking,the rating of electrical appliances determines the power utilized by them to work properly,accordingly the lights are switched on and off,this is done using igbt/mosfet,here a single phase pwm inverter is proposed using 8051 microcontrollers,2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer
