The Oklahoma Department of Corrections might soon have a long-forbidden security tool at its disposal. The Federal Communications Commission voted unanimously Tuesday to propose rules authorizing state and local correctional facilities to utilize cell phone signal jamming technology. Contraband cell phones, often used to coordinate organized crime and extort family members of prisoners, have plagued Oklahoma prisons for decades. In 2020, the Department of Corrections launched a pilot program to equip prisoners with a cell phone detection bracelet. “They’re so institutionalized, the only way they have a connection to the outside world is through the cell phone,” she said.
