Poor mobile phone signal jammer equipment may affect the routine work of other electronic products due to defects in the production process and design scheme, but professional equipment in technical professional places will never affect other electronic products. In the routine work, this is mainly because the professional mobile phone signal blocker equipment is not a simple circuit board splicing but a fully enclosed modular design structure. Each shielding control module matches a mobile phone data signal frequency band, and the mobile phone signal is shielded. When the device is running, each shielding control module only affects its corresponding frequency band, and will never cause any harm to other electronic products.
Yesterday, everyone was looking for data signals with their mobile phones. Why do they still need the 88 system? In fact, there are two levels of this objective fact. For those who can use mobile phones, it is natural to expect that the stronger the mobile phone signal, the better.

To this end, the Chengdu Examination Management Center cooperates with the public security department, and the security department conducts the construction and maintenance of standardized test centers for the county and district test paper command centers, installs the test room , realizes the full coverage of the signal shielding range, and accepts the implementation of security and confidentiality work. And meet the standard before the exam. At present, the city's examination room offices have achieved all-round, no dead ends, high-definition video surveillance. In order to ensure the fairness of the college entrance examination, the education department has equipped more than 600 mobile phone signal jammers gps in the examination room and more than 1,300 metal detectors.
