Background of Prison Jammer Construction: The background for the prison signal jamming solution stems from the critical need for security and communication control within the prison system. In the prison environment, the use of illegal communication devices such as cell phones and drones poses severe security challenges. Prisoners using these devices can make unauthorized contacts, such as coordinating escapes, directing external criminal activities, and receiving contraband, which severely threatens the security and order of the prisons. Moreover, illegal communications can also lead to unauthorized monitoring and interference with the prison from the outside.
