I don’t know if you have heard of a device called an exam signal jammer? This kind of machine is mainly used in the examination room. It is aimed at the use of exams such as college entrance examinations and postgraduate entrance examinations, because many students often take the exam. When I was here, special electronic signal methods were secretly used to convey information to the outside world, which caused very bad examination room problems and disrupted the fair examination room order. Therefore, major schools are now eager to equip this kind of equipment to prevent them from appearing in the exam. Improper means.
First, I will give you a brief introduction to the test signal jammer. Generally speaking, the function range of this kind of equipment is to block 2G, 3G, 4G mobile phone signals from 1 to 20 meters, and it can also block 2.4GWIFI signals. , So that people in the examination room cannot dial out and answer calls, and cut off the possibility of sending and receiving text messages. At the same time, the operation of this test signal jammer is very quiet and will not affect the examination room. The quiet environment causes the impact, so that the hidden dangers of the exam are solved quietly, and there is no need to worry. It does not cause any damage to the human body. After the mobile phone leaves the range, it can be used normally. There will be hidden dangers left. Today’s test signal jammers have been widely used in school examination rooms to prevent cheating, and more and more schools have a demand for them. Among them, Beijing Shenzhou Mingda is a company that has provided high-quality test signals for universities for many years. The manufacturer of the shielding device has a first-class technical team to provide high-performance technical support for the equipment, and to help and contribute to the examination order of the major examination rooms.
