High-Speed Train 5G Coverage System
System Architecture Product Application BACK
System Architecture
The Onboard 5G Coverage System relays and forwards multi-band, multi-standard 5G signals (TDD/FDD) from operators into high-speed train carriages. This ensures premium 5G coverage, effectively resolving issues like weak signals and poor communication quality caused by carriage attenuation, thereby enhancing passengers' network experience. Meanwhile, it helps extend the spacing between railway base stations, reducing both the number of ground stations and construction costs, while also lowering the difficulty of network optimization and long-term O&M expenses.
