Is the cell phone signal shielding installed in the school effective?
The campus test is to prevent students from using mobile phones to transmit information, leak test papers, cheating and other applications, and some are also to prevent teachers from escorting the test papers in the middle of the test paper, and leaking the test paper information content will cause less harm to the later test. Any campus is suitable for assembling a mobile phone signal jammer?
The cell phone jammer is to use the same frequency to read the downlink frequency of the communication base station on the mobile phone to carry out the same frequency interference signal. Any mobile phone signal from the surrounding communication base station will be harmful to the shielding effect of the mobile phone, so how to test the mobile phone signal on the mobile phone in the application of the mobile phone jammer What? In the hot summer in June, we will meet the high school entrance examination and the college entrance examination. In order to ensure the quality of the test, many campuses have already begun to prepare the examination venue in advance. In the process of preparing the test site in advance, there is a very important thing, that is, assembling the signal jammer. However, not everyone can assemble a signal jammer on a mobile phone. So, what should be paid attention to during the process of assembling the jammer on the mobile phone? In fact, the assembly itself will be relatively simple, but some small details before assembly determine the role of the latter signal jammer. For example, the natural environment around the assembly site. Then there is the relative height of the assembly.
In order to ensure the best function of the data signal, under normal conditions it is best to assemble 1 meter or less and 3 meters or less. The cell phone signal jammer is relatively small, and can be fixed on the roof or wall with ordinary screws. Naturally, it can also be used immediately on the table. However, under such conditions, the effect is not very good. After assembling, check whether the various parts are properly connected, and whether there is any problem with parts such as power supply. Finally, plug the power adapter into the power adapter power jack of the device, and immediately connect the 220V switching power supply. The following is debugging. If there is any problem, you can contact the manufacturer in a short time if you discover it during the debugging process. As long as it is produced by a professional manufacturer, it will usually be processed as soon as possible. If you encounter a pitted manufacturer, it is still recommended to find the manufacturer to return the product immediately. Not only the reputation is reliable, but the quality is also reliable. What's more, any problems will be dealt with as soon as possible to ensure that the interests of customers are not harmed.
