What signals can signal jamming block?
Whether it is the National Civil Service Test or the English Test Band 4 or Band 6, signal jammers will be used in the examination room to shield all kinds of cheaters. However, many people do not understand how the signal jammer works, or even what signals can be shielded by the shield. Today, let's popularize the following information about the types of signals that can be shielded by the signal jamming function.
At present, the common signal jammers in the market can basically block the mobile phone signals and WiFi signals of all operators in the market, including the unfamiliar WiFi, so as to eliminate any chance of cheating in the exam. In addition, the types of signals shielded by signal jammers are different according to the frequency band of the signal. Now the technology is more and more developed, and basically all shielding devices can block the 4G signal of mobile phones. However, the speed of technological development is too fast. Now 5G has gradually begun to be popularized in China. These signal jammers that can only shield 4G signals will also be upgraded to 5G shields.
There are also some outlaws who use UHF and VHF signals to transmit cheating signals. These two types of signals are generally used for walkie-talkies. However, these outlaws use these signals to make some low-power transmission machines, and then sell receivers to some candidates who want to cheat, and then transmit the test answers through the transmission machine. If the signal jammer adds interference modules of UHF and VHF signals to the equipment, Then it will be more perfect.
In the industry, Nanjing Baikang Electromechanical Technology Co., Ltd. is at the forefront of technology. The signal jammer supporting 5G signal shielding has been successfully developed and put into the market. The market feedback is also very good for the interference of mobile phone 5G signal. With the development of science, it has become inevitable that the technology of signal jammer will be eliminated by the industry if it is not updated. Signal jammers like this are generally used to block mobile phone signals. If you want to increase the types of shielded signals, such as WiFi signal, UHF signal and VHF signal shielding, and some special frequency band interference, our company can also tailor it for you.
