In today's information age, information protection and information shielding are very important. The use of shielding equipment such as signal shielding devices is of great significance in many occasions. Can Chip Bags Block Cell Phones As a shielding device that can be carried and used at any time, its utilization value is relatively high. Our company focuses on the research and development of various shielding devices, and also invests a lot of energy in the manufacture of signal shielding instruments. The signal jammers we manufacture have some improvements in function and use. Today, some shielding devices are used in many situations. A signal shielding device is a very common portable shielding device. In our usual exams, we often see teachers walking into the exam room with cell phone jammer devices. The use of signal shielding can block radio signals in the examination room, thereby preventing students from cheating. Some people may not be particularly familiar with signal shielding. Next, I will give you a detailed introduction to the functions and characteristics of signal shielding, as well as some methods of use.
The leap-forward development of modern communication technology requires technology and security enterprises to keep pace with the times, continuously develop and strengthen their own strength, and meet multiple challenges. The widespread popularity of mobile phones brings convenience to people, but also brings new problems of communication security and confidentiality. Eavesdropping, leaks, cheating in exam rooms, medical malpractice, gas station explosions and other incidents emerge one after another, accelerating the promotion and use of Can Chip Bags Block Cell Phones . Mainly used in examination rooms, prisons, gas stations, mobile phone bulletproof, oil depots, liquefied gas stations, detention centers, interrogation rooms, courts, labor camps, conference rooms, theaters, churches, libraries, school dormitories, special security and confidentiality occasions (confidential offices , negotiation rooms, mobile vehicles, mobile dignitaries and business dignitaries) scenes, etc., the status of mobile phone signal jammers in social life is becoming more and more important. In a cellular mobile communication system, the coverage area of the system is divided into several cellular areas. Base stations in each cell area are equipped with low-power transmitters that transmit signals that are only received by cell phones within the limited range of the cell. The transmitted signal is interfered by a certain intensity of the same frequency electromagnetic wave, and cannot communicate normally. The mobile phone and the base station must first establish a normal dialogue.
