cell phone jammer???

cell phone jammers are very much against the law in many countries. The US, UK and Australia to name a few. it is basically disrupting the cell phone that works by communicating with its service network through a cell tower or base station. Cell towers divide a city into small areas, or cells. As a cell-phone user drives down the street, the signal is handed from tower to tower. A jamming device transmits on the same radio frequencies as the cell phone, disrupting the communication between the phone and the cell-phone base station in the tower. It's a called a denial-of-service attack. The jammer denies service of the radio spectrum to the cell-phone users within range of the jamming device. this is all that you need to know about the technology.
