While the law explicitly prohibits the use of devices to actively block mobile phone signals, there is no provision prohibiting passive blocking of mobile phones. This means, for example, using wallpaper or building materials with embedded metal pieces to prevent mobile phone signals from entering or outside the room. The design of some buildings inadvertently blocks radio signals due to thick concrete walls or steel frames. I am in favor of installing portable jammers in prisons. Like other Attorneys General such as Christian Taubira, the new sealer François Bayer responded on Tuesday to the phenomenon of mobile phones in BFMTV and RMC prisons. The photos posted by his boss on social networks bring together photos of prisoners taken in their cells or smoking marijuana... Although the authorities have tried to curb this practice, this problem has persisted for several years.
This kind of indoor location tracking application can only be used for grocery sales, logistics efficiency, mobile games or large shopping malls, international airport terminals and other large buildings. Tracking the internal location of the device is also possible, but it is almost impossible. IndoorAtlas conducted multiple experiments in a tunnel less than 1,400 meters underground in a zinc and copper mine in central Finland. There, the system can use mineral deposits and many other anomalies that interfere with the earth's magnetic field to identify itself. Although this technology has been successful in some areas, it still faces great challenges in prison environments. The use of portable jammers can not only effectively prevent prisoners from using mobile phones for illegal activities, but also maintain the necessity of communication without affecting the daily management of prisons.
The application of portable signal jammers is not limited to prisons. As society's attention to the abuse of mobile phones continues to increase, more and more public places are beginning to consider adopting similar technical means to manage mobile phone use. For example, places such as cinemas, theaters, and conference rooms can install portable jammers to ensure that audiences and participants are not disturbed by mobile phones, thereby improving the overall experience and environmental quality. In addition, schools have also begun to explore the use of jammers in specific areas to help students concentrate and reduce the interference of mobile phones on learning.
However, the use of portable jammers has also caused some controversy. Some critics believe that although this technical means can solve the problem of mobile phone abuse to a certain extent, it may also bring privacy and security risks. For example, in an emergency, mobile phone jammers may hinder the making of emergency calls and delay rescue time. In addition, the widespread use of portable jammers may also lead to increased management and maintenance costs of communication networks.
Nevertheless, the potential of portable jammers in addressing the problem of mobile phone abuse cannot be ignored. With the continuous advancement of technology and the continuous expansion of application scenarios, this technical means will play its unique role in more fields. In the future, we need to find a balance between technical application and legal norms to ensure that the use of portable jammers can not only effectively manage the problem of mobile phone abuse, but also protect personal privacy and public safety. By continuously improving technology and policies, we can create a safer and more harmonious social environment while addressing the problem of mobile phone abuse.
