CH-4504 2G+4G+5G Portable Cell Phone Signal Detection Device
Product Introduction
The 2G+4G+5G portable cell phone signal detection device is designed for mobile terminal search and identification. Utilizing dedicated mobile communication physical layer and protocol stack technology, it transmits constructed wireless signals to establish communication with nearby mobile communication terminals, obtaining their relevant parameter information to enable detection and screening of mobile terminals. The device supports existing LTE and NR frequency bands deployed or reserved for re-farming.
Employing virtual base station technology, the device can detect and identify 2G, 4G, and 5G (NSA) mobile communication terminal equipment belonging to China's four major operators (China Mobile, China Unicom, China Telecom, and China Broadcasting Network) within specific areas with precise positioning. Mainly used by government agencies, military, prisons, aerospace, aviation and other security-sensitive departments, it provides an effective solution for "unauthorized devices" and "unregistered SIM cards," serving as technical assurance for communication and information security inspections.
Application scenarios
1. Shopping Malls: Rapid activation, precise positioning with unique RSRP algorithm achieving 0.1-meter accuracy, capable of accurate positioning in crowded areas.
2. Residential Complexes: More concentrated beam angle than traditional antennas, enabling precise positioning of specific floors in complex buildings, with support for underground parking garage operation.
3. Open Environments: Effective range up to 500 meters linear distance with clear directional guidance. Urban Villages: Capable of penetrating 5-6 buildings in complex urban village environments.
4. High-rise Buildings: Coverage up to 20 floors, compact size, easy portability, and flexible building scanning capability.
