Last month, cheating occurred in Shandong's college entrance examination. Some criminals confuse candidates, saying that they can provide cheating tools to help candidates pass the exam smoothly. But it was finally discovered, and as a result, the future of these candidates changed. So, in such a large-scale examination, how to eliminate the phenomenon of fraud? According to our understanding, what is called a signal jammer has been used in these years. Why is the black technology examination room ignal jammer so powerful?
The signal blocker in the examination room is mainly used to block the signals of various frequency bands of mobile phones. Usually, fraudsters need to send out the information of the test paper through the mobile phone, or they need to send the answers back through the mobile phone. Therefore, blocking the mobile phone signal is the best way. Now, many people want to opportunistically, through such means to pass the exam. However, this method is unfair to other students who study hard. Therefore, it is still more important for schools to install signal jammers in the examination room. Among the many manufacturers of signal jammers, which one is better? There is a company specializing in the production of signal jammers in Foshan, called signalstorer. Compared with other companies' products, their biggest advantage is that they have a larger choice. At present, their company has two types of signal jammers, built-in antenna and external antenna. At the same time, it also provides program services, which can relieve the school's worries. The reason why the signal blocker in the test room is so powerful is because of its own black technology. It uses the method of blocking the signal to block the mobile phone signals near the test room, so as to achieve the purpose of making the test fair and equitable.
