Interference technology has been developed, and prisoners of smuggling equipment are working hard. He said the tests could lead to wider use of technologies such as jamming prisons to freeze prisoners' phones, which has been described as a major security threat by officials across the country. Despite attempts by prisons and jails to prevent access to mobile phones through sophisticated metal detectors, prisoners are still looking for ways to smuggle mobile phones. Experts say the only way to prevent prisoners from using it for criminal activity is through signal jammer technology. Prison signal jammers have become a necessary complement to the tools needed to detain prisoners. Mobile phones are getting smaller and smaller, making it easier for prisoners to smuggle into facilities. This brings even harder work to already serving corrections staff, but cell phone blockers are the answer to prisoners' restrictions on using cell phones for potentially dangerous activities.
