Q: What is a cell phone jammer

A mobile phone jammer is a jamming device designed to block cellphone transmissions by disrupting the signal of a nearby cellphone tower. In the beginning, Signal jamming devices are used by police and the military to limit or disrupt communications. These portable jammers are available to allow their owners to prevent others within a certain radius from communicating via cell phone. Similar equipment is made to block signals in places where cell phone usage might not be desired, like theaters, churches, and operating rooms.

Q: Why Would Someone Use A Signal Blocker?

Mobile Signal jammers are often used in public areas where a phone call would be particularly disruptive because silence is expected, such as in restaurants, and movie theaters to prevent patrons from making calls while enjoying themselves.

Q: Do Signal Jammers Really Work?

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. It’s a called a denial-of-service attack. A signal jammer 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.
