Classic Case

  • Shanghai Metro Civil Communication System Design Project

    Upgrade the first phase of the civil communication system of Shanghai Metro Line 11 and use the innovative CDAS design to replace the 2G / 3G repeater or RRU in the original tunnel.
    The upgraded system supports 2G / 3G / 4G, effectively reducing the equipment footprint, reducing basic supporting resources such as fiber optics and feeder cables, and reducing the network construction cost of multi-operator and multi-system communication standards for co-construction and sharing in subway coverage.
