Telephones Installed Inside Prison Cells

In May of 2011 we wrote about a British prison that solved the problem of contraband cell phones by installing landline telephones in each of the cells of a jail. The results were fewer smuggled phones, less violence, and even fewer failed drug tests! Now another prison in the U.K is taking the same approach. As the authorities responsible for the prison state, the installation of a phone in each prison cell “may reduce the […]

Wireless Prison Payphone™ Briefs

Here is a summary of recent news articles regarding contraband cell phones in prisons around the world. I am calling this round up of articles, “Wireless Prison Payphone™ Briefs” because this is essentially what smuggled mobile phones in jails have become – a substitute for the current wall mounted prison payphones. Mobile phone jamming technology set for Scotland’s prisons: Mobile phone blockers, costing up to £1 million per prison, are being planned to stop inmates […]

Texas To Invest in Cell Phone Blocking Technology

This article discusses the TDCJ’s decision to investigate the viability of managed access contraband cell phone jamming. California, Mississippi and Maryland are also testing the technology. The impact of smuggled contraband cell phones in prisons has been significant. As the article states, “A couple of years ago, there were long lines at the pay phones—hours long. By this year, no one was using them, there were so many smuggled cell phones.” Update (3/15/13): Final testing […]

Prisons Battle Cellphone Smuggling

An interesting overview of the problems smuggled cell phones in prison create in jails throughout the United States. As usual however, the discussion of possible solutions focuses on reducing supply and signal jamming, but offers no consideration of a strategy reducing the DEMAND for contraband cell phones. By co-opting prisoners’ legitimate desire for more frequent and easier telephone access to family, prisons can reduce the overall demand for contraband cell phones and reduce the incentive […]

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 […]

Contraband Cell Phone Bill Headed To Governor

The legislation to curb contraband cell phones in California prisons is headed to the governor’s desk for signature.

Update – May 9, 2012: For an update on this legislation and the planned deployment of wireless managed access systems in the CDCR facilities to block contraband cell phones, see this […]

Prisoners’ Cell Phone Use On The Rise At FBOP

According to this article, the GAO has just released a study on the use of contraband cell phones in federal prisons. However the Federal Bureau of Prisons (FBOP) has not put in place or developed evaluation plans to measure the effectiveness of new technologies to address the smuggled cell phone problem. In fact, according to the GAO report, “BOP has a policy, called Pilot Initiatives, Approval and Evaluation, that identifies numerous criteria that should be […]

Cell phone jammers are being installed in all the prisons there to eliminate cell phone smuggling Jeddah: Prison authorities plan to install cell phone jammers in all jails in the Kingdom, an official said “The move aims to stop attempts by inmates to illegally communicate with outsiders to carry out criminal activities that would be harmful to other inmates,” assistant spokesman of the directorate […]
