The Cellular Jamming and Cellular Detection System, model IJS 6000 is an intelligent cellular jamming system designed to jam unauthorized cellular phones while permitting authorized cellular phones to operate, such as in a prison, courthouse, military installation, or specific environment where cell phone activity must be controlled. In correctional circles, it is known as the prison jammer or prison jamming system.

More than a cell phone jammer, the Intelligent Jamming System detects and manually or automatically blocks unauthorized usage of cell phones and/or cell phone activity in designated areas. The cellular detector composition functions as a cellular detection center and works symbiotically with the cellular jamming feature.

How it works
In order control cellular phone activity in any given area, an established configuration is designed. This is comparable to building a fence. However, instead of placing posts and fencing at a physical border, cell phone jamming hardware is deployed to operate in many (or few) buildings or areas. These cellular jamming units can deny access to a large number of cellular telephones at any given time within a group of separate buildings, or a complex of corridors, conference rooms, numerous small offices and private rooms.

These cellular jammers are in constant control by a central administrator that can permit or deny cellular communications. These cellular jammers are connected via a Controller Area Network (CAN) into a local network and managed by a Central Base Station (CBS). The Intelligent Jamming System controls every element, from detection, to alerting where and when an individual cell phone is attempting to establish communication, to blocking the calls. 

Remote Control Activation
The IJS can operate by remote control through the use of ON/OFF switching. Should the cell phone jamming components be located in buildings or areas away from the control unit, the Remote Control Activation can operate the cellular jammer from afar. 

Users
Users of the Intelligent Jamming System include prisons and detention centers, military bases, defense installations, border control checkpoints, as well as other physical areas that require information to be controlled or restricted.
