Are cell phone jammers in prisons obsolete? -- Taking Uruguay as an example

With the rapid advancement of communication technology, cell phone jammers, which have long been relied on in prison systems, are facing new challenges. In recent years, Uruguayan Interior Minister Eduardo Bonomi has publicly acknowledged that the signal jammers installed in prisons have gradually lost their original effectiveness due to the improvement and enhancement of cell phone signals. This change has raised public concerns about prison security, especially when high-risk prisoners are still able to issue criminal instructions through their mobile phones.

1. The original intention and current situation of jammers

As early as 2015, Uruguayan prisons began to install cell phone signal jammers, first in Libertad Prison and then in Comcar Prison. The original intention of installing these devices was to prevent prisoners from using mobile phones for illegal communications, especially when it comes to criminal command, drug trafficking and organizing violence. The presence of mobile phones is considered a great threat. By blocking mobile phone signals, jammers ensure that prisoners cannot communicate with the outside world through their mobile phones, thereby reducing the possibility of collaborative crimes inside and outside the prison.

However, with the advancement of mobile phone technology, especially as communication companies enhance signal coverage and improve service quality, these early jammers can no longer compete with modern communication technology. In an interview with Sarandi Radio, Bonomi said that after purchasing the mobile phone jammer, the operator quickly strengthened the signal, causing the jammer to gradually lose its original effectiveness. Prisoners can even identify which operators' signals can bypass the jammer and continue to use their mobile phones for illegal communication activities.
