Light rail systems, commuter railways, subways, and metro systems require advanced communications systems providing a large variety of services to ensure high levels of performance, reliability and safety. Inter- and intra-station voice and data connectivity, passenger information and public address systems, ticketing machines, video surveillance and security systems, and digital entertainment and display advertising screens are some of the many applications that need to be supported by the light rail and subway system communications network.
RAD multiplexers, cross connects, modems, and aggregation devices enable network planners and managers of light rails, commuter railways, subways and metro liners to maximize their network performance, while adding new services. Supporting SCADA and Tetra applications as well as real-time video, LAN and digital and analog voice, RAD’s multiservice access devices enable the transport of voice, video, low and high speed data, and real time information between control centers, trains, suburban stations, and emergency staff and services.
Because of the delay-sensitive nature of many mission-critical railway applications, TDM-based networks continue serve as the main transport technology for railway communications. RAD products have been engineered to maximize the capacity of these networks while supporting the transition to packet-based infrastructures where feasible. These products are certified to operate in the harshest environmental conditions typical of field deployments in these industries. RAD supports industry standards and offers reliable connectivity for a wide range of data rates over any available media – copper, fiber optic and wireless links.
