This Is a War

Prisons want jamming technology to stop criminal activity, but critics warn there would be dire consequences if jamming was allowed to propagate. In June the Department of Justice released a report that declared a solution to prevent criminal activity from happening within prisons: it successfully tested a jammer that would block mobile signals from smuggled cell phones inside a Maryland prison. Throughout the corrections world the news spread fast. For South Carolina Corrections director Brian […]

Prison Micro-Jamming Study Highlights Risks

T-Mobile recently submitted to the FCC a study comparing Managed Access Systems (“MAS”) and precision jamming systems (micro-jamming) as potential solutions to prevent contraband phone use in correctional facilities. This study was submitted to Docket 13-111, Promoting Technological Solutions to Combat Contraband Wireless Device Use in Correctional Facilities. The study provides an overview of MAS and micro-jamming solutions examining both technical and cost considerations. The paper finds that the cost to deploy and operate the […]

Prisoners Outwit Mobile Phone Blocking Technology

An interesting article in light of the recent letter submitted to the FCC by ten Republican governors  who want the Federal Communications Commission to give states more autonomy to apply technology that can stop prison inmates from using smuggled cellphones. Gov. Nikki Haley and her counterparts encouraged FCC Chairman Thomas Wheeler in a letter Monday to give them “flexibility and authority” to render such communication impossible. While the letter doesn’t explicitly say so, what the […]

CDCR Halts Roll Out Of Managed Access Cell Phone Jamming

This news tracks with reports elsewhere that this technology to block cell phone usage in prisons is problematic. An effective contraband cell phone strategy should focus on reducing demand, in addition to restricting supply. Corrections officials have shared with us the fact that at least 40% of the calls intercepted by these systems are to phone numbers on inmates’ approved calling lists. We suspect that an even higher percentage are to other family and loved […]

$11M Prison Managed Access Jamming Called “A Complete And Utter Waste Of Money”

A cautionary tale for prisons contemplating shelling out millions of dollars for managed access systems to jam contraband cell phones. A prison in New Zealand has spent over $11M (US) in installation and upgrades on a cellular signal jamming system that has not prevented the ongoing use of wireless devices. Taxpayers have forked out $17 million on cellphone jamming technology for prisons – but inmates continue to be caught with increasing numbers of contraband mobile […]

Caution Advised On Managed Access Jamming For Prisons

As we have written before, managed access cell phone jamming systems being tested in prisons around the world have been deployed with mixed results. In addition to requiring ongoing management and investment post deployment, they have a spotty record and not all vendor’s equipment works as advertised. Recently, the Cayman Islands issued a report on their managed access trial. According to the report, which is discussed in the article below, “The prisons service installed a […]

Australia Launches Contraband Prison Cell Phone Jamming Trial

An Australian-first trial of technology that will stop inmates from making calls from mobile phones they’ve illegally smuggled into jail has begun at a prison west of Sydney. The project trials the use of a Distributed Antenna System (DAS) to jam phones within the prison under the supervision of the ACMA and mobile phone carriers. The DAS system will jam the channels transmitting mobile phone signals within the prison but prevent disruption outside the prison. […]

“Managed Access” For Prison Contraband Cell Phones Is High Maintenance

According to a recent article, managed access systems (MAS) are not plug and play. They require ongoing systems management and staff time. This means ongoing cost, in addition to the high cost and operational challenges of installation. The Mississippi State Penitentiary in Parchman was the first prison in the country to use the Intelligent Network Access Controller (iNAC), which blocks service for contraband cell phones inside the prison walls. Being on the cutting edge involved […]

FCC Takes Up Technology Solutions To Contraband Cell Phones

Update: We have submitted our thoughts on this complex issue to the FCC. You can read them here and download the actual filing here. The FCC today issued FCC 13-58, Contraband Wireless Device Notice of Proposed Rulemaking (NPRM), to “remove barriers to the deployment and viability of existing and future technologies used to combat contraband wireless devices.” The NPRM discusses current technologies such as managed access, detection, jamming and wireless carrier service termination of identified […]
