Communication-based train control (CBTC) is used to improve traffic / mobility management and better control trains by providing accurate visibility regarding the trains location. CBTC is a mission critical application, dependant upon on a robust and secure train-to-ground communications technology.
TDD, synchronized based protocol to ensure uninterrupted connectivity between moving trains and the trackside network
Redundant architecture with no single point of failure
Secured system with customized air protocol, preventing standard Wi-Fi access
Optimized spectrum capabilities
