The cell phone owned by the prisoner allows him to contact external partners at the crime scene to coordinate the evacuation plan, thereby creating a life-threatening situation for the guards and the public around the institution. Correctional agency reports more often indicate that hidden mobile phones have been used to harass crime victims, or that prisoners repeatedly intimidate victims to persuade them to withdraw their charges or change their minds. history. To be honest, people increasingly want to live in a peaceful environment and enjoy a peaceful heart and a comfortable life. Therefore, do not want to be harassed by mobile phone calls, or in some cases, someone is following the mobile phone signal, travel is threatened or their privacy is attacked by WiFi. Therefore, they must interfere with the device to block cell phone and WiFi signals, and people who use signal jammers can achieve the ideal state they want.
