4, Product features

  This advanced signal jamming device features full-band signal shielding with seamless coverage across the entire frequency range from 8MHz to 6500MHz. Built on a Software-Defined Radio (SDR) architecture, it targets specific technical parameters including signal physical layer specifications and modulation methods to deliver precise and efficient jamming capabilities. The system effectively mitigates interference from 4G LTE and 5G SR/NSR mobile signals through advanced SDR algorithms and optimized jamming strategies that achieve lower power consumption, extended interference range, and enhanced overall effectiveness.​

  Utilizing innovative signal-level shielding technology, the device operates with low transmission power of just 350W total, significantly lower than comparable products on the market, eliminating the need for high-power suppression to generate effective interference. Its integrated antenna design consolidates all components into a single unit, enabling convenient one-handed operation with exceptional portability and practicality for field use.​

  Powered by a built-in lithium battery, the device provides an impressive 70 minutes of continuous operation. The modular design incorporates standardized interfaces that support plug-and-play modules with strong scalability and easy maintenance. The standard plug-in frame accommodates up to 8 independent business modules or 15 RF channels, allowing flexible configuration based on specific operational requirements.​

  Additional key features include a one-touch power function that supports both full-band and sub-band operation modes, effectively improving interference performance across different wireless coverage areas. The system offers high maintainability with support for software upgrades without hardware replacement, enabling quick adaptation to new 5G frequency bands and remote upgrade capabilities. A comprehensive self-diagnosis feature allows the software platform to monitor the operational status and alarm reports of each independent business module, facilitating rapid fault diagnosis and troubleshooting. The intuitive LCD touch screen interface supports external network port communication for both local and remote control capabilities.
