As the college entrance examination season is approaching, many schools are facing the problem of preparing for the college entrance examination examination room, such as the preparation of materials and machinery and equipment. These are all necessary matters to maintain the order of the examination room. However, what more schools now face is how to prevent the increasingly rampant cheating phenomenon, because some people choose to use "black technology" to implement cheating in the examination room using communication equipment. In response to this phenomenon, the examination Signal jammers also came into being, this kind of equipment can prevent the occurrence of electronic signal cheating in the examination room in an orderly manner.
But many people still don’t understand the principle of this device. In fact, its principle is not complicated. The function of the test signal jammer is to isolate the communication signal of the mobile phone and the 2.4G WIFI signal within the shielding range. This effect can isolate all communication signal cheating methods. This is because no matter how these "black technology" methods are and how concealed they are, cheating in the exam room requires sending and receiving information. However, within the shielding range of the test signal jammer, their communication equipment will be all "Lost connection", there is no communication signal, so installing this kind of equipment in the examination room can naturally eliminate all communication signal cheating methods. Now if you want to have a strong shielding effect in the exam room, you must choose a high-performance test signal jammer, so please contact Beijing Shenzhou Mingda for the price of the signal jammer. Years of operation have allowed them to reach in-depth cooperation with many customers. , Now it has received a lot of high-quality feedback, trustworthy and choice.
