Anyone dealing with the challenges associated with cell phone use by inmates should be aware of this project. “The purpose of the proposed technology development and evaluation effort is to design, implement and test an effective system for the detection and localization of cellular phones in correctional facilities. Correction officials have identified the problem of cell phones in prisons as one of the toughest issues they face. The phones, smuggled in by guards or family members and activated with hard-to-trace prepaid calling plans, are a lifeline for criminals and gang members to order hits, buy drugs and plan escape attempts from behind bars. We are developing a prototype Time Difference Of Arrival (TDOA) emitter detection and location system, and ultimately will demonstrate the system at Lawrenceville Correctional Center. The demonstrated system will be capable of detecting and locating cell phones in real time” (p. 2).
