Robert Johnson, a former corrections officer shot by an inmate, has spent 15 years advocating for the use of cell phone jammers in prisons. Despite resistance from wireless industry groups, the FCC is set to vote on a proposal that could allow state prisons to use jamming technology to combat contraband cell phones. Johnson's persistent efforts, including testimonies before the FCC, have brought the issue to this critical juncture. While some legal experts express skepticism, proponents believe jammers offer a more effective solution than current managed access systems.
