Collection: All About Cell Phone Jammer

Cell phone jammer are devices that are designed to block or disrupt mobile phone signals within a certain area. They emit radio signals that interfere with the communication between a mobile phone and its base station, effectively rendering the phone useless.

Types of Phone Jamming Device

There are several types of cell phone jammers, including passive jammers, active jammers, and hybrid jammers.

Passive Jammers: Passive jammers work by reflecting the mobile phone signal back to the phone, creating interference and disrupting communication. They are typically less effective than active jammers, but are also less expensive.

Active Jammers: Active jammers emit a strong radio signal that overpowers the mobile phone signal, effectively blocking communication between the phone and its base station. They are more effective than passive jammers, but are also more expensive.

Hybrid Jammers: Hybrid jammers combine the features of both passive and active jammers, creating a more effective and versatile device.

They are also used in prisons and other correctional facilities to prevent inmates from using mobile phones to coordinate criminal activity.
