Overview
Fan-less 5G-R / LTE-R Interworking Network for High-Capacity Railway Communications
Embedded Files
Growing data traffic from railway digitalization and AI-based services
Higher transmission rates required beyond existing LTE-R capabilities
Direct application of commercial 5G to rail causes high cost and low flexibility
Railway-optimized 5G-R / LTE-R interworking network provides broadband communications
Integrated use of 5G-R and LTE-R improves dedicated railway network efficiency
