Smart City Rail

Urban rail transit not only relieves the pressure of urban traffic, but also facilitates the travel of the urban population. In many urban rail transit systems, the signal system is called the brain of urban rail transit, which is an important guarantee to ensure the safety of train operation and realize driving command. The signal system requires real-time and accurate information transmission between vehicle-ground systems, so the construction of a safe and reliable large bandwidth and low-latency vehicle-ground communication network has become the consensus of the subway industry. With the maturity of LTE private network, LTE-M private network has become an indispensable subsystem in the urban rail transit signal system.

  • Savings on investment

    One network is multi-purpose, and one network can meet the requirements of all vehicle communication and reduce overall investment.
  • Ensure safety

    With 1.8G special frequency band, the system has high reliability and can ensure the safety of train operation.
  • Easy to maintain

    A single RRU can cover 1.2KM, and there is less equipment in the tunnel, which is convenient for later maintenance.
  • Business guarantee

    QOS guarantee, minimal switching and transmission delay, 9-level QOS guarantee mechanism, to ensure the transmission quality of column control services
