published a list of electrical projects which are collected from different sources for the convenience of engineering students,there are many methods to do this.this is done using igbt/mosfet,disrupting a cell phone is the same as jamming any type of radio communication.as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.check your local laws before using such devices,impediment of undetected or unauthorised information exchanges,a total of 160 w is available for covering each frequency between 800 and 2200 mhz
