Now almost all examination rooms must install such a device, especially now that the important day of the high school entrance examination and college entrance examination is approaching. , this equipment becomes even more important. In fact, installing a signal jammer is also a delicate job, but applying it is the most important thing. But what issues should we pay attention to during use? Below, TopSignaljammer will popularize the issues you need to pay attention to when using signal jammers.
In fact, after turning on the jammer, the signals in the surrounding specific area will be jammed. The editor reminds you that it is best not to use mobile phones around the examination room, because the signal shielding equipment in the examination room is all radio waves, and there are many types of electromagnetic waves. It won't harm the application of other things, but it will directly affect the application of smartphones. Therefore, there is no need to use a mobile phone Internet test signal jammer near the examination room.
Pay attention to the use distance. Although the test signal jammer is very reliable, it should be noted that it is not omnipotent. First of all, most of the use distance of the jammer is only 20 meters long. Generally, a small classroom of tens of square meters can use a cell phone jammer, but if the range is larger, the application effect will not be obvious. The relatively strong signal interference is its advantage and disadvantage. Because this kind of signal shielding mainly blocks the data signal between the mobile phone and the communication base station through signal interference. Therefore, some signal jammers with relatively good characteristics may work too well and directly affect the applications on surrounding mobile phones. But it is because of that that the fairness of the test can be guaranteed. When purchasing an exam signal jammer, be sure to buy it from a reliable manufacturer. Ordering from a reliable manufacturer is more guaranteed. So you can choose the signal jammer from topsignaljammer.com.
