In recent years, with the promotion and construction of standardized examination room projects, mobile phone signal jammers have become a must-have technical support product in the examination room, and they will be installed in each examination classroom in a fixed installation manner, abandoning the need for every examination in the past During the period, the method of temporary distribution and unified collection after the examination is adopted. Then the following question came out, what should be paid attention to when the mobile phone signal jammer is installed in the examination room?

The examination room is a number of classrooms used in the examination room. The installation positions of cell phone jammer in the classroom are usually as follows: above the blackboard in front of the classroom, on both sides of the blackboard, on both sides of the blackboard at the back of the classroom, and in a certain area of the classroom. Relatively centered position on one side of the wall. No matter which location you choose to install, you should pay attention to at least the following:

1. The installation height should exceed the height of a person raising his arm as much as possible. Specifically, it should not be lower than 2 meters. There are two reasons for this: one is to ensure that after the shielding signal of the mobile phone signal jammer is emitted, it can be used in the classroom. When propagating the signal, you can get all-round coverage without encountering obstruction. The second is to prevent artificial malicious contact or damage to the mobile phone portable jammer as much as possible;

2. The power cord that supplies power to the mobile phone signal jammer should adopt standard electrical work standards. It is necessary to install a protective tube for the power cord. Never connect a power cord casually. The power cord connection should be well insulated and protective measures;

3. In classrooms equipped with mobile phone signal jammers, if equipped with digital multimedia teaching equipment, especially those using wireless mice in computer teaching, it is recommended to replace the wireless mouse with a wired mouse, because the current mobile phone signal jammers Almost all have the function of shielding wireless WIFI and Bluetooth signals. If you need to use a wireless mouse to operate the computer during the test, you will not be able to complete the mouse operation normally due to the signal shielding effect.

4. Pickups and playback speakers are generally installed in the examination room. When choosing the installation location of the mobile phone signal jammer, the distance between the pickup and speakers and other equipment should be opened to the greatest extent. This is because the mobile phone signal jammer is in the After starting up and working, there will be a certain degree of electromagnetic radiation within the range of one to two meters around the transmitting antenna, which may have a negative impact on the normal operation of the above-mentioned equipment.
