A signal blocker used in prisons is a device used to block wireless communication signals, mainly in prisons and other custodial facilities. These devices can prevent inmates from using cell phones, wireless networks and other wireless devices to communicate inside the prison.
The working principle of the signal blocker is to interfere with the normal operation of wireless communication by transmitting interference signals. It emits a certain electromagnetic signal that prevents wireless signals from outside the prison from being reached or received, thereby preventing wireless communication inside the prison. This can effectively prevent prisoners from communicating illegally with the outside world, planning criminal activities or other violations.
The purpose of using signal blockers in prisons is to maintain safety and order in prisons. By restricting prisoners' wireless communications, they can prevent them from continuing to participate in criminal activities, contacting outside accomplices, or organizing escape operations. This helps to keep people safe and prevent and respond to crime.
