Application of mobile jammers
In order to deal with these problems, Sandip Goel, director general of Delhi Prisons, decided to upgrade the jammer system in the prison from 3G to 4G. His goal is to prevent prisoners from using mobile phones in prisons and ensure the safety and order of prisons. Mobile jammers interfere with the communication between mobile phones and base stations by emitting radio waves of the same frequency as mobile phone signals, thereby preventing mobile phones from receiving or sending signals. This technology can be applied not only in prisons, but also in public places such as schools, cinemas, and libraries, helping us regain the good times of face-to-face communication.

Mobile jammers can block mobile phone signals in class, allowing students to concentrate on listening and improve their learning efficiency. In addition, in exams, jammers can also prevent students from using mobile phones to cheat and ensure the fairness of exams.

Mobile jammers can create a signal-free zone in these places to prevent the use of mobile phones, thereby keeping the environment quiet. This not only helps maintain public etiquette, but also allows us to enjoy face-to-face communication more.
Application in prisons
In prisons, prisoners use mobile phones to carry out illegal activities, which brings great challenges to prison management. The example of Delhi Jail shows that prisoners use 4G SIM cards to make VoIP calls and even video calls through WhatsApp to pass information to the outside world. Mobile jammers can effectively prevent these activities and ensure the safety and order of the prison. In addition to installing jammers, prison authorities have also stepped up patrols and inspections to ensure that no mobile phones are illegally brought into the prison.

Although mobile jammers are widely used in many aspects, their use also brings some controversy and challenges. First, the use of jammers is illegal in many countries and regions. It is usually illegal to sell, own or use jammers without government permission. Second, the use of jammers may interfere with some important communications and bring potential safety risks. For example, using jammers on buses may interfere with the communication between the driver and the dispatcher, affecting the handling of emergencies.
Summary
Mobile jammers play an important role in modern society, especially in maintaining order in school classrooms, keeping quiet in public places, and ensuring prison safety. However, their use also brings legal, public safety and technical challenges. How to use jammers reasonably while safeguarding the public interest has become an important issue we need to think about. We should give full play to the advantages of jammers on the premise of legality and compliance, while avoiding their potential risks and ensuring social safety and order.
