For various standardized test rooms, is one of the indispensable facilities. Many colleges and universities are now purchasing signal GPS jammers. One thing that should be paid attention to when purchasing test room signal jammers is the test room signal What frequency bands must the blocker block? Use custom frequency bands? Since the popular mobile phones used today contain a variety of frequency bands, in order to do a good job of shielding data signals in the examination room, the shielding frequency bands of 88 in the examination room must be all-round, mainly including GSM/DCS/CDMA/PHS/3G (TD -SCDMA/CDMA2000/WCDMA)/4G/5G data signal and WIFI network signal, if some test centers have special requirements for the shielding frequency band of the shield, for example, it must be able to shield 5.8G Wi-Fi, wireless walkie-talkie UHF/VHF segment, wireless invisible For earphones, bone conduction earphones, wireless network digital communication system receiving equipment, etc., you must purchase a test room signal isolator suitable for custom frequency bands.
The test room often installs , in fact, it is also to better shield the data signal of the mobile phone, so at this time, everyone only needs to use the mobile phone to carry out the examination and there is no problem. However, in this process, there are some areas that must be paid attention to.

The inspection is over. Secondly, the mobile phones you use also need to be comprehensive in terms of operators. For the mobile phones that are generally used in your daily life, China Unicom and Telecom mobile phones need to be ready to complete the test, so as to ensure that everything is safe, except for preparing a sufficient number of mobile phones in advance. We are carrying out the test. The process also requires the assistance of professional and technical personnel. Many people are likely to think that the test is to see if the mobile phone has a data signal, and we can do it ourselves. However, after the signal shielding device in the examination room is installed, the standard of harm is quite high, and shielding blind spots may occur in many locations. It is obviously unrealistic for everyone to try one by one. Professional staff will understand where the problem of shielding blind spots is very likely to occur because of their rich and colorful work experience, so that they can ensure that they are problem-oriented in the case of inspection, and the overall efficiency will appear higher.
