CDCR To Block Prison Cell Phones Via Managed Access Jamming System

The CDCR recently issued a bid for its inmate telephone services and made the installation of wireless managed access jamming systems in its prisons a requirement for the bidders. Global Tel*Link (GTL) has won that bid and will therefore be bearing the cost of installing these systems. Given the high cost of this selective jamming technology and GTL’s commitment not to raise the cost of calls for prisoners, either the CDCR is taking a much […]

Wireless Prison Cell Phone Jamming Blocks Neighbors’ Service

The use of wireless jammers to block contraband prison cell phones is one of the many supply-side initiatives being investigated and deployed in prisons around the world. As shown by these news items, this frequently results in the loss of cellular service for the homes and businesses located near the prisons. This calls into question the viability of using this technology to eliminate the use of contraband cell phones. Recently, in response to reports of […]

Prisons Battle Cellphone Smuggling

An interesting overview of the problems smuggled cell phones in prison create in jails throughout the United States.

Prison Cell Phone Jamming Not Working

An article describing some of the technical problems with contraband cell phone jamming in a prison. Unlike the managed access systems used in the United States, this Cayman Islands implementation blocks all cellular signals. Except, it doesn’t.

Despite Cell Phone Jamming, Killer Uses Facebook In Prison

No technology is perfect, and that includes cell phone jamming technology. The real issue here is how compromised is the wireless blocking system installed at Parchman to combat contraband cell phones? The meshDETECT secure cell phone service has no internet access available so prisoners cannot access Facebook or Twitter. An inmate inside a Mid-South prison has been able to take pictures and post them online, despite a high-tech blocking technology put in place to keep […]

Prison Officials Hope Jammers Find Illegal Phones

This article discusses the problem of illegal prison cell phones in the State of Texas. As with most states, the initial approach to deal with the problem is to try jamming contraband prison cell phones. The cost of this approach has yet to be quantified however. State corrections officials said Friday that a test of cell phone detection technology at a Southeast Texas prison where an inmate used a contraband phone when he escaped last […]
