No matter which kind of exam is a major event, tens of millions of candidates have passed the two-day exam after years of hard work and hard work. A good exam is a good university, good resources are chosen, and a bad exam is chosen. Lack of resource opportunities. Many people think that this method is good, but there are also many people who think that such results are only temporary, too excessive and unfair. Although there are disagreements on the fairness of the college entrance examination, the fairness of the college entrance examination system has been used for many years and has become more and more perfect, especially on the issue of fairness. At the very least, the college entrance examination is the best way for underachievers to progress!
In order to ensure the fairness and justice of the examination and protect the vital interests of the majority of examinees, mobile phone signal jammers are used in the college entrance examination examination room. Like other important exams, the use of cell phone jammer in the college entrance examination examination room is also of great concern, so many misunderstandings in the use must be paid attention to.
1. In different applications, the test panel signal monitor will have different effective shielding ranges. This problem is closely related to the field strength at the scene. Different types of mobile phones may not have the same shielding range at the same location, so the choice should be based on the actual situation.
2. The factors that affect the shielding range include but are not limited to: distance, direction, obstacle-free objects relative to the base station, wall materials of the site building, installation height of the shield, installation specifications, etc., and other factors should be paid attention to.
3. Each antenna has a frequency band identifier, which must correspond to the frequency band identifier on the host, and before opening the shield, it must be ensured that the connection of each antenna is reliable, and the device cannot be used without the antenna.
4. It is normal for the shield to run for a long time, and the surface temperature can rise to over 40 degrees.
5. The mobile phone signal jammer is generally installed at a height of 1.8 to 2.5 meters, and the installation location should be between the target shielding area and the target shielding area without obstacles. If the antenna is to be installed vertically upward on the wall-mounted type, the antenna can be folded 90 degrees and then vertically upward.
6. During the use of the mobile phone signal jammer, in order to avoid the possible interference of some electronic devices, the following commonly used equipment should be used within 1 to 2 meters.
