Teldat H1 Rail
Rugged wireless routers for advanced broadband services on trains
Enable secure broadband connectivity in trains to provide
multimedia managed services, including security, telemetry,
passenger Internet access, and more.
The Teldat H1 Rail series router is an integrated rugged
communications platform that enables highly available, reliable and
secure broadband cellular connectivity aboard trains. This router
combines a robust mechanical design, adequate for its installation in
19-inch racks aboard moving trains, with a versatile broadband wireless
(wireless WAN and Wi-Fi) and wired (Ethernet) communications port
layout. The router is powered by Teldat’s Internetworking Software
(CIT), offering a robust enterprise-class IP protocol stack for the
efficient implementation of multiple managed VPN services on a
mobile access. The Teldat H1 Rail router installed base can be centrally
managed by Teldat’s network management platform (TeldaGES), or
seamlessly integrated into existing IT network management systems.

Key Features
Reliable LTE wireless-WAN broadband performance
Cellular interfaces provide uninterrupted connectivity and application continuity when travelling through poor coverage areas. On longer
trains, more than one H1 Rail can be deployed along the train, thereby providing higher bandwidth, better redundancy and spatial separation
of the antennas for uninterrupted communication. Short areas without coverage (eg. tunnels) may not affect the whole train length at a time,
so communication is maintained with spaced-out equipment.
Automatic selection of the best available connection, based on parameters such as network availability, signal reception level, quality of
service, etc.
Passive link supervision: the signal coverage, the technology availability, the IP transmission service status and the transmission activity
are permanently controlled
Poll-based link supervision: not only failures but also degradations on the 4G communication are detected, notified and corrected. The
router controls error rate, link latency and jitter to guarantee utmost performance on the streaming transmission (i.e. real-time IP-CCTV
image transmission or voice)
