There are some venues where we should be able to destroy or restrict this kind of Internet artificially to prevent the harm caused by the mobile data network. Under such preconditions, the conference hall Spam Cell Phone Blocker will be born from time to time. The essence of the mobile phone signal jammer is that it performs magnetic induction interference on the WiFi network, which is indispensable for mobile phone communication, so that the mobile phone cannot access the network license, so it cannot accept the information content transmitted from the data network, and it cannot be used. The content of information is sent out according to the Internet, but it does not harm the data signal caused by the mobile phone. In order for the wireless signal jammer to reasonably interfere with the mobile data network, it must be ensured that the magnetic field strength of the data signal transmitted by the jammer should be much higher than the magnetic field strength of the mobile signal BCH in the area where the interference is performed. Therefore, the addresses of the same jammer application are different. The size of the reasonable area for interference is different. Generally, the closer it is to the communication base station, the stronger the magnetic field strength of the local BCH. The area where the jammer can interfere reasonably is small. Generally, the radius of interference is only 0.5~9m; The farther away the magnetic field strength of BCH is relatively weak, the larger the radius of the jammer to achieve reasonable interference, which can reach more than ten meters to several tens of meters. Therefore, the size of the local BCH magnetic field strength should be considered before applying the jammer, and then the position, total number and composition method of the jammer should be decided according to the size of the interference area.

The high school entrance examination date is approaching, and many schools will purchase and install Spam Cell Phone Blocker to deal with the possible cheating behavior of students using mobile phones. Since there will definitely not be only one test room as a test center, it is necessary to purchase and install mobile phone blockers in the test room when purchasing in batches. What precautions should be taken when purchasing mobile phone jammers in the examination room in bulk? When purchasing test room signal jammers in bulk, in fact, the main focus is to choose the right professional test room cell phone jammer manufacturer, because professional test room jammer manufacturers have many years of R&D experience and are very familiar with test room jammers. What parameters do you need? Mobile phone jammers can be customized by manufacturers according to their needs, and it is also clear what kind of mobile phone signal jammer is suitable for what kind of test environment. The key is in terms of price, because it is factory direct sales, eliminating the need for middlemen to earn the difference. And because it is a bulk purchase, plus a mobile phone jammer manufacturer can provide more discounts.
