LTE-M Broadband Trunking Network Helps Smart Urban Rail Construction.
Urban Rail eLTE Private Network Solution
The urban rail industry requires train-to-ground wireless networks to carry services such as train control, train dispatching, PIS/CCTV and trackside IoT etc. The traditional urban rail communication systems require : 2 RATs (Wi-Fi and Tetra) and 4 networks (Three Wi-Fi networks are used to carry CBTC, PIS, and video surveillance services, and one Tetra network is used to carry dispatching).
Traditional solutions face many challenges: CBTC control signal over Wi-Fi are easily interfered and are not stable in high-speed scenarios. The traditional TETRA solution supports only voice services and cannot meet the requirements of video services. The network is complex and difficult to maintain.
LTE-M (Metro) is a 4G TDD LTE-based wireless train-to-ground communication solution for urban rail transportation. It ensures continuous, reliable, secure, and uninterrupted urban rail communication and carries multiple services such as CBTC, trunking dispatch, PIS, and CCTV. Simplified networking reduces maintenance difficulties. Simplified networking reduces maintenance difficulties. Dedicated frequencies and multi-level QoS mechanisms are used to ensure system security and reliability, and stable operation of key CBTC services.
Benefits
One network carries multiple services
Stable and reliable, 99.999% availability
High-speed movement up to 200 km/h
Powerful QoS capability to ensure CBTC
