FCC to vote on allowing cellphone jammers in state prisons

What the vote could change

According to Engadget, the FCC will consider a rule allowing state and local incarceration facilities to opt into using cellphone jammers. The technology would remain optional, not mandatory, for these facilities. Currently, only federal entities are permitted to deploy jamming tools under strict conditions.

The Federal Bureau of Prisons has been testing "micro-jamming" in federal prisons since 2018, targeting unauthorized cellphone use without disrupting external communications. The new rule, if adopted, would extend similar options to state and local facilities while establishing standards to prevent harmful interference outside prison walls.

Why the FCC opposed jammers

The FCC has historically banned the use of jamming technology by non-federal entities due to risks, including potential interference with emergency communications and the possibility of jammers being exploited by malicious actors outside prisons. These concerns led the agency to prohibit widespread deployment of such tools.

In July 2025, the FCC delayed implementing a cap on prison phone call rates, signaling ongoing scrutiny of telecommunications policies affecting correctional facilities. The planned vote suggests a shift in priorities, weighing security risks against the need to curb illegal inmate communications.

Requirements for deployment

If the rule is adopted, correctional facilities would need to meet specific standards before deploying jammers. This includes demonstrating that the technology does not cause harmful interference outside the designated areas, such as neighboring communities or emergency response zones. The requirement aims to balance security needs with broader public safety concerns.

This shift in FCC policy reflects a growing recognition of the security risks posed by illegal cellphone use in prisons. For founders and operators in the telecommunications and public safety sectors, the vote could open a new market for compliant jamming technologies. However, the requirement to prove non-interference with external communications means that vendors will need to invest in precise, localized solutions. If adopted, the rule could also set a precedent for how other countries address similar challenges in corrections facilities.

Key takeaways

• State and local prisons in the US may soon have a legal pathway to deploy cellphone jammers, creating opportunities for vendors specializing in secure telecommunications tech.
• The FCC’s requirements for non-interference testing could raise the barrier to entry for providers, favoring companies with proven, precise jamming solutions.
• The policy change underscores the broader trend of regulators balancing security needs with potential risks—useful context for startups working in regulated industries.
• Federal testing of 'micro-jamming' since 2018 suggests a preference for targeted solutions, which could guide product development in this space.
