RISC-Based Multi-WWAN Computers

One of the biggest challenges in modern rolling stock systems is establishing a solid and dependable communication network between a fast-moving train and the stations along the track. Wireless train-to-ground communication is the link that connects many advanced train services such as automatic train operation (ATO) and passenger Wi-Fi systems. In order to meet the stringent requirements of these systems, wireless devices must be able to consistently deliver reliable connectivity and sufficient bandwidth to support all the applications that count on train-to-ground communication systems.

Moxa’s newly launched UC-8580 is a RISC-based multi-WWAN industrial computing platform designed specifically for seamless vehicle-to-ground communication. The UC-8580 is provided with four slots for installing wireless modules. Three slots support 3G/ LTE cellular modules, and one slot supports a Wi-Fi module. Each cellular module is provided with two SIM card slots to support redundant cellular network communication and geo-fencing SIM card selection, which you can implement by leveraging the built-in Wireless Manager, a Moxa software utility for cellular and Wi-Fi management.

The UC-8580’s single-sided I/O design is ideal for space-limited vehicle applications. With its front-side access panel design, the computer allows for convenient installation and replacement of wireless modules, SIM cards, and mSATA cards without needing to unmount the entire unit from the wall, thereby simplifying maintenance.

The UC-8580 uses an open platform based on Debian 8 with Linux Kernel 4.1, allowing solution providers to manage software packages via Debian’s APT, or develop software applications with Moxa’s API Library and GNU C Library.
