Signal jammers in prisons: Will the communications of neighbors be affected?

In recent years, as criminal activities in prisons have continued to increase, many countries have begun to install signal jammers in prisons to prevent prisoners from conducting illegal activities through their mobile phones. cell phone jammer Signal jammers can effectively block mobile phone signals and reduce criminal behavior in prisons, but their use has also caused some controversy, especially the potential impact on residents living around prisons.GPS jammer Claudio Valencia, an electrical engineering scholar at the University of Santiago, Chile, explained how these devices work and responded to concerns that they may affect the communications of neighbors.

How signal jammers work

The basic working principle of signal jammers is to emit a jamming signal that blocks normal communication between mobile phones and base stations. signal jammer After receiving the jamming signal, the mobile phone cannot connect to the base station, making it impossible to make calls or send messages. Professor Valencia pointed out that the jamming signals emitted by these devices can be controlled very precisely, and if installed properly, they will only affect communication devices in a specific area, such as mobile phones in prisons, without interfering with the communications of surrounding residents.

Valencia further explained: "If we use directional antennas and point them at the interior of the prison, it will not actually affect the communications of nearby residents. The design and installation of such equipment need to consider how to minimize the impact on the surrounding environment. If operated properly, the signal jammer will not cause significant interference to mobile phone signals outside the prison."

Reducing potential impact on residents

The application of signal jammers faces a key problem, that is, how to effectively block mobile phone signals inside the prison without affecting the normal life of surrounding residents. Jorge Sandoval, a civil electrical engineer at the University of Chile, pointed out that the use of directional antennas can help solve this problem. By more precisely controlling the direction of signal transmission, signal jammers can be concentrated in specific areas of the prison, thereby minimizing the impact on the outside world.

He added: "By using more directional antennas, signal jammers can be better focused on target areas within the prison, thereby reducing interference with external communication devices. This improvement in technology can help alleviate neighbors' concerns about communication interruptions."

Installation date and safety measures

Although the installation of signal jammers has been approved, the exact start date has not been made public. The main purpose of these devices is to combat illegal activities within prisons, especially the use of mobile phones to direct crimes. Pablo Jacques, president of the Carabinieri Association, said that they are currently waiting for further integration of technology to ensure that these measures can be effectively implemented.

Jacques pointed out: "We are looking forward to new technological combinations to ensure that the signal jammers are clearly targeted. This is what we expect and it is a necessary step to combat criminal activities in prisons."

In response to the protest actions that prisoners may take due to this new measure, the Carabinieri Association has ordered the suspension of leave for some staff and is ready to reinforce at any time.
