MDPB-15XL

The SZMID MDPB-15XL is an advanced mobile phone signal blocker designed using Software Defined Radio (SDR) architecture to provide highly targeted and efficient interference for 2G, 3G, 4G, 5G, WiFi, and Bluetooth signals. With its signaling-level interference strategy, the MDPB-15XL disrupts communication by targeting key technical characteristics such as signal modulation and physical layer definitions. This precise approach allows the jammer to effectively block mobile communications and wireless transmissions within a radius of 1 to 30 meters, causing mobile devices to lose network access, preventing calls, texts, and data services, while ensuring that other electronic devices remain unaffected.

Unlike traditional jamming techniques, the MDPB-15XL employs an intelligent system that automatically detects and scans communication frequencies and signal strengths within the shielded area. This enables point-to-point interference on critical communication channels, enhancing energy efficiency by 10 to 100 times compared to older sweeping methods. The system is capable of shielding all mainstream communication bands from 700MHz to 6GHz, ensuring complete coverage of mobile phone signals, WiFi, and Bluetooth connections. Additionally, its low transmission power ensures effective signal blocking with minimal energy use, extending coverage while maintaining a high interference efficiency.

One of the standout features of the MDPB-15XL is its ability to shield only the downlink signals from base stations, affecting only mobile terminals without disrupting the uplink communication of base stations. This is especially useful for TDD system downlink signal blocking, preserving public communication safety while achieving effective signal jamming.

The device is compact, lightweight, and user-friendly, requiring no complex setup—simply plug and play. Its adaptive algorithm automatically adjusts to different environments and frequency bands, eliminating the need for additional configuration. The MDPB-15XL also supports remote management through standard TCP/IP protocols, enabling real-time monitoring and adjustment of device parameters via a network connection.

The jammer comes equipped with an alarm function, where an LED indicator provides a steady red light in the case of any system abnormality. Its screen displays key operational parameters, including the IP address, for easy management. The MDPB-15XL’s emission power is lower than traditional jammers, significantly reducing radiation levels, ensuring it is safe for human health.

In summary, the SZMID MDPB-15XL is a powerful and precise solution for environments requiring reliable and efficient communication disruption, offering advanced interference control, energy efficiency, and ease of use, making it an ideal tool for securing sensitive areas and maintaining operational privacy.
