How to build a cellphone Jammer


A cell phone jammer is an instrument used to prevent cellular phones from receiving and transmitting the mobile signals to a base station. When used, the jammer effectively disables cellular phones in the area. These devices can be used in practically any location, but are found primarily in locales where a phone call would be particularly disruptive. These include churches, mosques, libraries, movie theaters, meeting rooms, and other places where silence is expected.

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.
