How to cell phone jammer work?
The cell phone jammer is a device which transmits the signals to the same frequency. The jamming section is successful when the area of the mobile phone signal is disabled if the jammer is on. The first jamming device was developed and used by the military for communication purpose. Where the planed commanders use RF communication to control their power and also in enemy communications. Nowadays the mobile users are increasing day by day, hence the mobile phone jammer devices are becoming civilian by comparing with the electronic devices to disable the mobile signals in specific locations.
Cell phone jamming devices overpower the cell phone by transmitting a signal on the same frequency and at a high enough power that the two signals collide and cancel each other out. Cell phones are designed to add power if they experience low-level interference, so the jammer must recognize and match the power increase from the phone.
