Digi provides reliable, high speed, secure cellular connectivity products for rail applications including Positive Train Control (PTC), wayside device communication and on-board passenger internet access.
Railways have seen a tremendous increase in focus in recent years, driven primarily by government funding of requirements for technology overhauls relative to safety, efficiency of infrastructure and increased ridership initiatives. New advances in wireless technologies have allowed Digi to provide highly reliable, high speed, secure cellular connectivity solutions for trains and remote trackside equipment.
Having a robust, reliable on-board wireless back-up network in case of 220 MHz network outage is a federal requirement for Positive Train Control (PTC) compliance. The Digi TransPort WR44 RR, our rugged, all-in-one cellular router with multi-carrier support (via Gobi technology), is designed for maximum back-up of railway communications.
Rail operators need the ability to establish either primary or backup wireless communication to a variety of remote wayside equipment like hot box detectors (HBDs), automatic equipment identifiers (AEIs), wheel impact load detectors (WILDs) and other sensors. Through diverse device interfaces such as multiple Ethernet ports and serial ports, the Digi TransPort WR44 R connects wayside equipment to cellular networks with multi-carrier support for access and monitoring.
Internet access is the ultimate in railway passenger convenience. Digi's rugged, 3G/4G cellular routers with built-in Wi-Fi access point are built to provide an exceptional customer experience. Key benefits include a VPN with stateful firewall, which means content could be filtered by providers, and a splash page that could include a company logo, information, offers and a customer log-in.
