Many people use cell phone signal jammer to prevent the distraction of mobile phones. These devices are often used in schools and prisons to prevent inmates from using their phones. They can also be used as a safety measure, as they block all communications from the inside of a prison to the outside.

The technology behind signal blockers is similar to that of cellular communication. In order to jam the signal from any cellular phone, you must know how the devices communicate. Wireless devices communicate with a service network through a base station or tower, which divides cities into cells. The towers communicate with one another through a series of radio frequencies. A signal blocker works by disrupting this signal by jamming the same frequencies as the wireless devices.
