With the rapid development of modern communication technology, the use of mobile phones has been widely popularized. While mobile phone communication is convenient for people, it also poses new challenges to communication security and confidentiality work. In recent years, major accidents such as eavesdropping, leaking secrets, cheating in the examination room, medical malpractice, gas station explosion and so on have occurred in our country.
1. The mobile phone jammer adopts a special advanced technology approach. When it is in the working state, it can automatically form a shielding magnetic field within the specified range, so that the mobile phone cannot be dialed out or connected, so as to achieve the purpose of forcibly disabling the mobile phone. The advent of the mobile phone signal jammer has completely solved the various hazards caused by calling mobile phones, enabling people to enjoy the speed and convenience brought by high technology to human beings without causing interference to the surrounding environment, and only have an effect on mobile phone communication signals , no interference to other electronic equipment.
2. Application place of mobile phone jammer
Audio-visual venues: theaters, cinemas, concerts, libraries, recording studios, auditoriums, etc.
Security privacy: Prisons, courts, examination rooms, meeting rooms, funeral homes, government agencies, financial institutions, embassies, etc.
Health and safety: industrial factories, production workshops, gas stations, gas stations, hospitals, etc.
3. Working range of mobile phone jammer: 0-20 meters (radius)
4. Introduction to the principle of mobile communication:
The working principle of the mobile phone is as follows: within a certain frequency range, the mobile phone and the base station are connected by radio waves, and the transmission of data and sound is completed with a certain baud rate and modulation method.
5. Introduction to the principle of mobile phone shielding device
According to the above communication principle, the mobile phone shielding device scans from the low-end frequency of the forward channel to the high-end at a certain speed during the working process. This scanning speed can form garbled code interference in the message signal received by the mobile phone, and the mobile phone cannot detect the normal data sent from the base station, so that the mobile phone cannot establish a connection with the base station. The mobile phone shows phenomena such as searching the network, no signal, and no service system.
6. Basic functions:
1) Slow start function: After the mobile phone shielding device is powered on, the working power rises from zero to stable within 4 seconds.
2) Shielding function: After the activation is completed, the mobile phones within the effective range will be shielded within 35 seconds.
