MDPB-40S built-in antenna signal shield is our factory adopts foreign advanced technology, mainly for the domestic college entrance examination, adult college entrance examination, self-study examination and various colleges and universities in the exam process, some criminals use mobile phones to cheat the status quo, and at the same time combined with all kinds of middle and senior middle school students use mobile phones to send text messages during class time. As well as the annoyance and noise brought by mobile phones in serious places such as meeting rooms, concert halls and theaters of various sizes in government agencies and enterprises, According to the actual situation of domestic mobile communication carefully developed high-tech products, it can block GSM/DCS/CDMA/PHS/3G(TD-SCDMA/) in the radius of 1-30 meters (1-800 square meters) CDMA2000/WCDMA)/4G/5G mobile phone signal and WIFI wireless signal, so that the mobile phone can not play and answer,WIFI can not work normally, but will not interfere with the work of other electronic teaching equipment, mobile phone out of the partition range, you can resume normal use.

Interference capability: shielding 2G/3G/4G/5G/ 2.4GWIFI and other frequency bands, can also be customized according to customer requirements (5.8GWiFi, walkie-talkie UHF/VHF segment, wireless invisible headphones, bone conduction headphones, wireless digital transmission receiving tools, etc.).

EPM enhanced energy management design to ensure the stability and accuracy of high-frequency signals, reliable power supply to ensure the reliable performance and long-term life of the shield, equipment integrated design, built-in power supply and antenna, will not be affected by high-frequency signals, easy installation and storage, not easy to damage.

The use of ACOPS chip overheating prevention system to avoid overheating of the shield due to improper use by users or high ambient temperature on site, effectively ensure the long-term stable work of the shield and ensure the shielding efficiency.

It is composed of the latest chip components and integrated circuits, with advanced performance, easy installation and use, with air flow hole and active heat dissipation design, combined with air trough type aluminum fin heat dissipation, to ensure long-term continuous work.

The average transmission power of each channel is 4~5W, and the effective shielding distance is 1-30 meters (depending on the signal strength of the use place).

Need customization items: The device can add LED LCD display, automatic detection system, automatic signal detection on startup, detection of machine voltage, current, temperature, signal normal or not.

The equipment is equipped with corresponding LED indicator to observe whether the machine is working normally.

Built-in silent fan to ensure no noise interference in the examination room environment.

The body comes with an ergonomic design handle for easy handling.

The transmitting power of the shield is similar to that of the mobile phone signal transmission, and the wireless transmission does not have any damage to the human body

Optional network control, through the intelligent shield management system to control the switch of equipment, timing switch
