The day of the college entrance examination is approaching day by day, and for the schools preparing for the college entrance examination room, the preparation time is also decreasing day by day. Among them, it is an urgent matter to start the test signal blocker. We all know that it is a kind of ability. A machine that isolates the communication signal and installs it in the examination room can effectively prevent the use of mobile phones and other communication devices to cheat. However, when it comes to the shielding device, it is necessary to talk about the size of its shielding range, and when it is actually put into use, the shielding The size of the range is uncertain, why is this? Here we will reduce to the laboratory data problem.
In fact, many people don’t know that the data on the shielding range in the manual attached to the test signal shielding device they bought is actually laboratory data. Most of the machines on the market have a radius of about 0 to 50 meters. That is, the area is 10 to 250 square meters, and this data refers to the detection in an open place, and there is no base station within 500 meters, the actual effect is uncertain. Because it depends on how far the base station near the examination room is from it, the impact will be different for different distances within 500 meters. Of course, the best way is to actually test it. In fact, no matter whether it affects the scope of the test signal jammer, when choosing this kind of equipment, you must choose a more high-performance machine, so customers are welcome to come to Beijing Shenzhou Mingda to consult the signal jammer price. This is a professional production expert, and has been highly praised by customers for many years of development. We are waiting for the arrival and cooperation of our customers.
