Since their launch, cell signal blockers have been favored by various institutions. Initially, they were not designed for examination rooms, but were specifically used in high-security places such as prisons. Prisons require a high degree of physical and information security, and cell signal blockers play a vital role in this regard, ensuring the information security and privacy protection of prisons.
In prisons, cell signal blockers can effectively prevent prisoners from illegally communicating with the outside world through mobile phones, prevent information leakage and plan jailbreaks and other illegal acts. Through the signal sent by the blocker, the prison can block the transmission of all mobile phone signals, ensure that the communication inside the prison is completely under supervision, and ensure the safety and order of the prison.
In recent years, many schools have also begun to install cell signal blockers to prevent students from using mobile phones in class and affecting the normal teaching order. The popularity of high-tech devices such as mobile phones has indeed brought a lot of interference to students' learning. Many students are even addicted to mobile games and social networks, which seriously affects their learning efficiency and physical and mental health. In order to maintain a good learning environment, many schools have decided to install mobile phone signal jammers.
During the exam period, the role of mobile phone signal jammers is particularly obvious. Although the school clearly stipulates that mobile phones are prohibited during the exam, some students still take the risk of bringing mobile phones into the examination room. By installing mobile phone signal jammers, even if students bring mobile phones into the examination room, they cannot use the network to cheat, thus maintaining the fairness and justice of the examination.
The selection of mobile phone signal jammers is not only about appearance, but also about its internal structure and performance. Depending on the antenna, signal jammers can be divided into two types: external antenna and internal antenna. The cell phone jammer with an external antenna has a stable signal and good transmission effect, but the external antenna is easily physically blocked and damaged, and occupies a large space. The shell of the jammer with an internal antenna is sturdy and durable, occupies a small space, and the signal is relatively stable, which is suitable for places with limited space.
The application of mobile phone signal jammers in prisons and schools has significantly improved the information security and order of these places. In prisons, they ensure the absolute security of information and prevent illegal communications. In schools, they maintain a good learning environment, prevent students from being addicted to mobile phones, and improve the fairness of exams. With the continuous advancement of technology, mobile phone signal jammers will continue to play an important role in more special occasions to ensure information security and order in various places.
