MDPB-40S

The SZMID MDPB-40S is a high-performance mobile phone signal jammer designed to meet the specific needs of educational institutions, government agencies, and enterprises. Developed with cutting-edge technology, this device addresses common challenges such as mobile phone cheating during exams, text messaging in classrooms, and disruptive phone use in sensitive areas like meeting rooms, theaters, and concert halls. It effectively blocks mobile phone signals within a radius of 1 to 30 meters (covering up to 800 square meters), ensuring that mobile devices cannot make or receive calls or use Wi-Fi, while leaving other electronic teaching and business equipment unaffected.

The MDPB-40S provides comprehensive interference across 2G, 3G, 4G, 5G, and 2.4G Wi-Fi frequency bands. For more specific requirements, customization options are available to block 5.8G Wi-Fi, UHF/VHF walkie-talkies, wireless invisible earpieces, bone conduction headphones, and other wireless transmission tools.

The device integrates EPM enhanced energy management, ensuring stable and accurate high-frequency signal blocking and reliable performance over long periods. With its built-in power supply and antenna, the compact system is easy to install and store, designed to remain unaffected by high-frequency signals. To ensure continuous operation, it employs the ACOPS chip-based overheating prevention system, which protects against improper use or high ambient temperatures.

Constructed with the latest chip components and integrated circuits, the MDPB-40S offers advanced performance, active heat dissipation, and an ergonomic design for easy handling. Each channel delivers an average transmission power of 4 to 5 watts, providing an effective jamming distance of 1 to 30 meters, depending on local signal strength.

Customization options include an LED LCD display and automatic detection system that monitors voltage, current, temperature, and signal status, ensuring optimal operation. The device features silent fans to maintain a noise-free environment, making it ideal for use in examination halls or quiet locations. The jammer's transmission power is similar to that of mobile phones, posing no harm to human health.

Additionally, the system can be equipped with network-based control, allowing operators to manage the jammer remotely through an intelligent shield management system. This feature supports remote on/off switching and scheduled operation for greater flexibility and control.

In summary, the SZMID MDPB-40S is a versatile, easy-to-use mobile phone jammer, providing reliable interference across a wide range of frequencies. Its high-performance design, user-friendly features, and customization options make it the ideal solution for maintaining exam integrity, security, and peace in sensitive environments.
