What is Cellular Jammer? How does it work?

A mobile phone jammer or blocker is a device which deliberately transmits signals on the same radio frequencies as mobile phones, disrupting the communication between the phone and the cell-phone base station, effectively disabling mobile phones within the range of the jammer, preventing them from receiving signals and from transmitting them. Jammers can be used in practically any location, but are found primarily in places where a phone call would be particularly disruptive because silence is expected, such as entertainment venues.

It might be hard to follow this process without first understanding cell phone signals. Cell phones work by sending signals to cell phone towers. The cell tower that receives the signal depends on the cell phone’s location. Cell towers divide their workload by honing in on specific areas. So when you travel with your cell phone, your cell phone sends signals to different towers. 

The jamming device works by sending radio frequencies to the same tower. It will overpower the cell phone signal by mimicking your cell phone. Basically, it sends out a signal that is the same frequency as your phone. This signal is powerful enough to outmuscle your phone’s signal. The jamming device’s signal and your cell phone signal eventually collide. This process causes a lapse in communication between the cell phone and the cell phone tower.
