GSM-R



Our GSM-R Distributed Antenna System (DAS) is vital for ensuring seamless communication and safety in railway tunnel environments. By extending GSM-R signal coverage, it facilitates uninterrupted communication between train drivers, railway staff, and control centers, enhancing operational efficiency and emergency response capabilities.
