Communication control

CH-5500 4G+5GNSA code detection and positioning equipment uses a fully independently developed multi-core ARM and FPGA architecture to implement 4G+5GNSA wireless communication technology and base station functions, thereby realizing the data collection of 5GNSA+4G users.

Ø4G full network access (B1/3/39/40/41/42/43) +, overseas customized B2\B4\B7, etc.

The 4G integrated 4-band portable positioning device adopts a multi-standard portable integrated design, which is the first in the industry, supports the full 4G frequency band and adapts to various complex network environments, greatly improving the efficiency of case handling. It has good adaptability to dense urban villages and high-buildings. The system consists of a portable host and an operating mobile phone. It is the first 4G integrated small portable positioning system in the industry with high maturity, superior performance, strong adaptability, easy operation, and can be put into practical application.

The 4G Portable Investigation System is a new generation investigation products which is just for TDD/FDD 4G network terminals of the three domestic mobile communication operators. Based on the working principle of 4G wireless communication base stations, the product actively collects the relevant information of 4G mobile phone users in the coverage area through the capture and processing of LTE air port wireless signals, and sends it to the background management system installed by the staff's portable mobile phones through WiFi. After the background analysis and processing, real-time interception, positioning and code investigation of suspect users are realized.
