BSH-TYPPE full-function mobile phone signal shield is our latest high-tech shielding product specially designed for the examination room, which can effectively block (interfere) all mobile phone signals (CDMA, GSM, D S S, P C S, PHS, 3G, 4G, 5G), WIFI (WLAN), Bluetooth / 2.4G communication, wireless network, (QQ and Weibo, etc.), to cheat, ensure the fairness of the examination, and create a fair competition environment for students.

I. Functional Features:

* Effectively block CDMA (China Telecom), GSM (China Mobile, China Unicom), DCS (1800MHz), PHS (1900MHz), 3G, 4G, 5G and other mobile phone signals and WIFI (WLAN), Bluetooth / 2.4G communication, wireless network (QQ and wechat, etc.), pinhole camera signals

* Green environmental protection, electric magnetic field strength is far lower than the national standard, no impact on the human body

* Fine division of each frequency band, only disturb the downlink frequency, will not cause interference to the base station

* Unique heat dissipation and ventilation hole and dual fan design, plus overheating protection system, to ensure a long-term safe, continuous and stable work.

* Built-in switch power supply to ensure the stability and accuracy of the signal

* Built-in antenna, simple to operate, turn on the power supply can run automatically

* Slow start circuit design, effectively avoid the phenomenon when starting

* Choose imported high-performance integrated circuit and patch elements, using imported automatic patch machine and reflux welding machine processing, assembly line production, stable quality and performance

II. Technical indicators:

* The technical indexes have passed the safety and quality certification of the National Communication and Navigation and Beidou Satellite Application Products Quality Supervision and Inspection Center. After the strict detection of Hebei Radiation Environment Management Station, the intensity measurement values of all measurement points meet the requirements of "30-3000MHz m and 3000MHz-1.22 f 1 / 2V / m" in the Electromagnetic Environment Control Limits (GB8702-2014).
