When technologically advanced smartphones are widely used as cheating means, the maintenance of discipline and order in the examination room will also increase the difficulty and pressure. This requires full use of the role and performance advantages of wireless signal jammers to ensure that mobile phones cheat All kinds of behaviors can be completely eliminated. I believe this is of great help to ensure a fair environment in the examination room.
Especially after you are familiar with the working principle of wireless signal jammer equipment, you can reflect the performance advantages of professional equipment from different angles. After all, this is of great help to strengthen the technical strength of the equipment. As we all know, the technical level of signal shielding has been greatly improved, especially the scope and field of application have been greatly expanded. Since we have mature conditions and technical elements in all aspects, it is also necessary to solve the problem of signal shielding. In addition to playing a vital role, the advantages of highlighting the role of wifi jammer are quite obvious. Finally, after the shielding module is fully utilized, the shielding effect will be further improved, and comprehensive technical support can be provided for some activities (school exams) that need to shield mobile phone signals. Further familiarity with the working principle of wireless signal jammers will ensure The functions and effects of shielding equipment are fully utilized.
Why do the examination rooms choose radio frequency jammers with built-in antennas?
With the continuous development of science and technology, the mobile network has also been updated several times, from the original 2G mobile phone network to the current 3G, 4G and 5G mobile phone mobile signal network. At the same time, the radio frequency jammer is also constantly updated. Radio frequency jammers are mainly used in school exams, college entrance examinations, and places where the use of mobile phone communication equipment is prohibited, so why do the jammers in the examination room choose radio frequency jammers with built-in antennas?
First of all, the built-in antenna is more beautiful than the external antenna
Secondly, after the interferometer with the metal casing of the external antenna is turned on for a long time, the machine will generate a relatively high temperature, which also has certain potential safety hazards, but now it is made of high-plastic materials, which is a good solution solved this problem. The built-in antenna has higher environmental protection and safety.
Finally, the radio frequency jammer with built-in antenna is easy to carry, has better practicability and lower damage rate. Because the external antenna jammer is prone to antenna loss or damage, the built-in antenna radio frequency jammer has both the transmitting antenna and the power supply built into the shell, so that the operation is very simple and convenient to carry. It can be used normally after the power is turned on, and there is no need to disassemble the antenna after use, just turn off the power, which greatly improves the use effect and later maintenance costs.
