Puebla government to install signal jammers in San Miguel prison

The government of Puebla, Mexico, will install eight cellular signal jammers at the San Miguel Penitentiary Center to prevent inmates from using mobile devices for illicit activities. According to a tender issued by the state Finance Secretariat, the equipment is designed to block various technologies, including GSM, 3G, 4G, and 5G.

Each jammer will feature six independent channels to operate across different frequency bands. The system is intended to restrict mobile communications within the authorized perimeter to prevent crimes such as telephone extortion. The technology is specified to avoid interfering with public security frequencies, police radios, or telecommunications in surrounding areas.

A monitoring center will be established under the Subsecretariat of Penitentiary Centers to allow for real-time supervision, fault detection, and remote operation control. This move follows reports from the Puebla Public Security Secretariat that 933 mobile phones had been seized in state prisons as of July.
