Modern railway transport depends on advanced communications technology for ensuring safety, security and uninterrupted service. RAD Data Communications has a portfolio of robust, long-range railway communications solutions for high-speed and main line railways, urban metros and subways, and light rail.
 
RAD’s diverse and innovative standards-based products provide cost-effective connectivity for all mission-critical applications and services required in today’s railway environment, including end-to-end voice and data transmission along railway lines, GSM-R backhaul, video surveillance, variable message signs (VMS), control equipment, signaling and alarms. RAD’s railway communications solutions provide reliable transport of the information necessary for railway operators to make critical control decisions instantaneously. They also enable passengers to access real time information so critical for planning journeys and making alternative plans in the event of delays or mishaps.
