As the college entrance examination season is approaching, many schools are facing the problem of preparing for the college entrance examination room, such as the purchase of materials and equipment, which are necessary to maintain the order of the examination room. However, what more schools are now facing is how to prevent the increasingly rampant cheating phenomenon, because some people choose to use "black technology" to use communication equipment to cheat in the examination room. In response to this phenomenon, the examination The mobile cell phone jammer also came into being. This kind of equipment can prevent the occurrence of electronic signal cheating in the examination room in an orderly manner.

Recently, many students reported that they have seen a new batch of new machines installed in the classrooms of the school, which made many people wonder what it is. In fact, it has been vigorously promoted and installed in the classrooms of the examination room. The equipment of the signal jammer is now used in the major examinations in the school, and when the college entrance examination is approaching recently, basically every examination room has been installed with this kind of equipment. This is to prevent more and more problems in recent years. The more serious the phenomenon of cheating occurs, the candidates can take exams with peace of mind in a stable and orderly examination room.

Signal jammers generally do not disturb candidates
The frequency bands of general 4G signals and WIFI signals are between 800MH and 26000MH, and the test WiFi signal blocker is a device that can effectively block all communication signals in this frequency range, so whether it is a 4G signal or a WIFI signal, It's all out of the question. And now facing the arrival of the college entrance examination, some candidates who do not focus on their studies and want to cheat by illegal means, the wifi jammer is undoubtedly a powerful tool to break their intentions, which can maintain the normal order of the examination room and allow the examination room The test takers can take the test with peace of mind, and there is no noise during the use of this equipment, which can ensure that the test process will not be disturbed by the test takers.

Many people are also very curious about how the test 4G jammer counteracts the occurrence of these cheating phenomena. In fact, based on the method of cheating by using communication equipment, no matter what method is used, it is necessary to send and receive signals in the test room. However, in the test The signal jammer cannot receive any signal in the effective shielding range, because it has the function of isolating communication signals and WIFI signals. This range is generally about 0 to 50 meters in radius, and a low-power device can just cover it. We live in one classroom, so all we can see is that each classroom has a computer installed. In fact, for schools, when buying test signal jammers, you must choose high-performance ones, because in this way, a strong shielding effect can be guaranteed and every part of the test room can be covered.
