The principle behind interrupting the cell phone is similar to jamming other types of radio communication. In order to use a cell phone, a signal is sent from the phone to the cell tower. There are several cell towers in a city. As a cell phone user moves in an area, the signal is handled by one tower to another.

By blocking cell phone signals, students cannot become distracted by their phones. In addition, they cannot cheat by sending text messages to one another during exams.
The operation of jammers should be the responsibility of the concerned vendor to avoid any local tampering at the examination centre. The jammers effectively disable cellular phones. They transmit on the same radio frequencies as mobile phones, thus disrupting the communication between the phone and the mobile phone base station in the tower.
