Active & Reactive RF Jamming to combat Contraband Cellular Phones in Prisons and Government Facilities

Problem: Correctional Facilities experience a high rate of contraband cellular phones being smuggled in.

Problem: Convicts continue to carry out criminal activities in Prison, by communicating to criminals outside of Prison using illegal Cell Phones.

Captured phones from a Prison

Solution 1: Active RF Jamming using Directional RF initiation to maximize coverage inside the facility, covering RF

Shadow zones, while minimizing neighboring areas inside and outside of the

Prison.

hybrid Detector Jammer

Below: Covert Jammer installation into Exit Sign Housing

Solution 2: Reactive Detection and RF Jamming

The Detector Jammer listens to the RF Environment. Upon confirmation that a mobile phone is actively sending or receiving a call, the sensor triggers the RF Jamming System. The sensor powers off as the Jammer activates, severing the link between the local service provider and the mobile phone.

Attributes of the Detector Jammer

THE DETECTOR JAMMER CAN BE CONNECTED TO A SINGLE CONTROL CENTER

THE CONTROL CENTER SOFTWARE CAN BE STORED ON A DESKTOP OR LAPTOP

INDICATORS DISPLAY SYSTEM STATUS, INCLUDING ALARMS

THE GUI WILL SHOW WHICH DETECTOR JAMMERS WERE SET OFF

THE USER MAY PROGRAM HOW ACTIVE JAMMING MAY TAKE PLACE BEFORE REVERTING TO THE DETECTION MODE (FACTORY PRESET IS FOR 5 SECONDS)

WITH AN RS-485 INTERFACE (dual wire differential simplex serial connection) THE SYSTEM MAY USE 1 MASTER AND MULTIPLE SLAVES:

ALL DETECTOR JAMMERS MAY BE INTER-CONNECTED USING THE SAME CABLE, AND THEN CONNECTED TO THE CONSOLE AT THE CONTROL CENTER

ANTENNA DESIGN IS DIRECTIONAL IN BOTH VERTICAL AND HORIZONTAL PLANES. THE SIGNAL IS STRONGEST DIRECTLY IN FRONT OF THE ANTENNA, WHICH IS OF A FIBERGLASS FACE PLATE CONSTRUCTION

THE RECEIVER IS NOT ABLE TO OPERATE WHILE THE JAMMING FEATURE IS ACTIVELY ENGAGED IN RESPONDING TO ACTIVE MOBILE PHONE OPERATION, AS IT GOES DORMANT UNTIL THE PRE-SET TIME EXPIRES
