MDPB-40G mobile phone signal blocker also known as mobile phone signal processing equipment/mobile phone signal jammer/mobile phone signal blocker/mobile phone signal isolator/conference security machine. MDPB-40G is mainly aimed at the status quo of 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, and combined with the status quo of various middle and senior middle school students using 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 range of 1-40 meters (1-200 square meters) CDMA2000/WCDMA)/4G/5G mobile phone signal,WIFI wireless signal and 700MHz (radio and television 5G frequency), so that the mobile phone can not play and answer,WIFI can not work normally, but will not interfere with other electronic teaching equipment work, the mobile phone left the partition range, you can resume normal use.

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

The EPM enhanced energy management design ensures the stability and accuracy of the high-frequency signal, and the reliable power supply ensures the reliable performance and long-term life of the shield.

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, and guarantee long-term continuous work.

The average transmission power of each channel is 4~5W, and the effective shielding distance is 1-40 meters (depending on the signal strength of the use place).

The equipment adopts high heat dissipation precision aluminum alloy shell, which is durable and durable to ensure long-term uninterrupted and reliable operation. The front three cooling fans and the side exhaust air design ensure stable power output to a greater extent, and the safety factor is higher and the use is more assured. 7. The antenna adopts high-gain omnidirectional antenna, which has strong signal acceptance, wider coverage and more stable output.

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.
