LTE-Based Train-to-Ground Wireless Communication System: The LTE-M (LTE for Metro) system, as an urban rail transit train-to-ground wireless communication solution, provides continuous, reliable, secure, and uninterrupted communication support for metro operations. It is capable of carrying multiple services, including trunking dispatch, CBTC (Communication-Based Train Control), passenger information systems, and video surveillance, significantly simplifying network architecture complexity and reducing maintenance challenges. This makes it an ideal solution for the integrated service bearing requirements of rail transit systems.

By utilizing dedicated frequency bands and a multi-level QoS (Quality of Service) mechanism, the LTE train-to-ground wireless system effectively ensures the security and reliability of operational services. It offers strong anti-interference capability, high security, and seamless high-speed handover, providing robust support for the stable operation of critical rail transit communication services.

Broadband Trunking Dispatch System: With the rapid development of urban rail transit and the advancement of intelligent operations, there is a growing demand among operational departments for multimedia dispatch, real-time video transmission, and high-speed data services. Traditional narrowband systems are no longer capable of meeting the operational requirements of modern rail transit systems. In this context, broadband trunking dispatch systems based on LTE technology have emerged to address these evolving needs.

The broadband trunking dispatch system complies with B-TrunC and MCX standards, supporting point-to-point calls, group calls, and broadcast modes. It provides reliable communication between fixed users in urban rail operations (such as control center and depot dispatchers, station attendants, etc.) and mobile users (such as train drivers, safety personnel, maintenance staff, etc.). This system effectively supports voice trunking communication requirements for the safe, high-density, and efficient operation of urban rail transit. It plays a crucial role in ensuring operational safety, improving transportation efficiency, enhancing management standards, and elevating service quality.
