Practical application of shielding device in examination room
In recent years, test room shields have appeared many times in school classrooms, churches, conference rooms and other places, and have become indispensable equipment. Its essence is to interfere with the wireless signal of the communication equipment, so that the mobile phone cannot access the Internet, cannot receive the signal from the base station, and cannot send out signals through the network to achieve the effect of disconnection. These days, almost everyone knows about shielding equipment, and basically everyone who has taken the test should know about it. In general, before and after the classroom, you will find its traces when you enter the examination room for inspection. It is not just as simple as simply blocking mobile phone signals, but more to give candidates a level playing field. The installation of the test room isolator may result in no network signal in an area, but it will not affect the transmission of the base station signal at all.
Exams are a way to test your knowledge. Passing the test can reflect the student's learning status and other abilities, in order to ensure the fairness of the test results. The examination room has strong disciplinary constraints, and is equipped with a chief examiner, invigilator, etc. to supervise the complex process of the examination, plus a series of anti-cheating equipment such as the examination room shield. Fundamentally block the source of the signal to prevent cheating.
The use of shielding equipment should be viewed rationally. The test room jammer sends interference signals in the designated frequency band, which interfere with the mobile signal received by the mobile phone, so that the mobile phone cannot connect to the network. On the other hand, the order of the test room is completely guaranteed.
