The system consists of signal control platform software, signal control base station, collector, and distributed signaling-level antenna equipment. RF transmission uses optical fiber and feeder transmission media. The signal control platform software uses TCP/IP protocol and Category 5 cable transmission media. The control system redirects the operator's public network 2G, 3G, and 5G signals to 4G, then controls the 4G signal, and obtains the terminal ISMI code to achieve blacklist and whitelist control and precise positioning.

Low-radiation distributed architecture: The system is based on base station-type directional analysis technology and uses distributed multi-point transmission of the antenna feed system. The transmission power does not exceed 1/300 of the traditional shielding device, and the electromagnetic radiation is lower than that of the mobile phone.

Full-area and full-standard: Solve the problem that other control methods are difficult to control in scenarios where the operator's network signal strength exceeds -50dBm and 2G/3G/5G control, and realize full-standard control.

High precision: The control positioning accuracy is less than 0.2 meters.

Adaptive: It can automatically detect changes in the external network environment and adaptively adjust its own parameters to ensure reliable operation of the system;

Smooth and upgradeable: The system can support the current 2G, 3G, 4G, 5G and other standards to provide expansion interfaces.

High reliability: To ensure the stable and reliable operation of the distributed intelligent communication control system, the system provides a mature network management and equipment monitoring platform (OMC), which can monitor the operation status and parameter configuration of each network element in real time to avoid the impact of human damage on the communication control effect. The internal communication control of the prison is a complex system. It must be an integration of multiple systems, follow the principle of integrity, and be an economically reasonable and resource-optimized system solution.

Security: The security of the system should be high. The security mechanism of the entire system should be fully considered during design and development. The built system should have security and confidentiality. Not only strict authority management should be carried out, but also advanced and reliable security and confidentiality measures should be taken.

Advancedness and maturity: The system should adopt advanced and mature technologies and equipment to build a system with excellent performance and advanced technology, which can not only ensure the reliable application of the current system, but also adapt to the requirements of future technology and business development. Advancedness can ensure that the system meets international and domestic standards and is easy to expand and develop; maturity means reliability, stability and good cost performance.

Reliability and stability: The connectivity of the entire system guarantees data transmission and storage, ensuring long-term reliable operation of the system.

Scalability: Taking full account of future development, the system can be expanded as needed to prevent repeated investment, and the system leaves sufficient room for future expansion, upgrading and integration. Hardware and software products adhere to the principle of standardization and adopt national and international standards.

Convenience: Integrated deployment of control, detection and positioning, few nodes, single wiring, simple construction and installation, high system reliability, and convenient maintenance.

Full standard: full coverage of mobile, Unicom, and telecom operators, 2/3/4/5G (NSA, SA) full standard network control;

Full frequency band: full coverage of B1/B3/B5/B8/B/28/B34/B39/B40/B41\7/N78\B42 frequency bands, no omissions in control;

Ultra-multi-carrier: up to 24 carriers with the maximum concurrent number, the strongest in the industry, to ensure that no off-book machines are missed.
