Overview

The MAR-2000 is a compact, simple, and programmable RISC-based wireless mobile router with strong wireless routing capabilities. With a built-in GPS module, HSPA+ cellular and 802.11a/b/g/n wireless capabilities, independent power switches on its cellular module connectors, and high thermal tolerance, the MAR-2000 is compliant with a portion of EN 50155 specifications. The built-in 32 MB NOR Flash ROM and 512 MB SDRAM give you enough memory for installing your own application software, the 512 MB NAND Flash can be used to provide additional data storage, and the CompactFlash socket is available for adding more memory when needed. The built-in GPS module supports geo-fencing functionality, making it ideal for managing wireless connections in cross-WAN environments often associated with rolling stock and other vehicular applications.
When a train travels to a different region, it often encounters switches that support different wireless interfaces, such as Wi-Fi, UMTS, and HSPA+. The MAR-2000 uses multiple-WAN support and backup functionality to ensure that your wireless connections are always available, stable, and reliable.
As an added bonus, the MAR-2000 series includes wide temperature models designed to operate reliably in extreme environments with temperatures ranging from -25 to 70°C.

White Paper

An Intelligent Wireless Routing Platform for Rolling Stock

More and more, the rolling stock industry is moving towards wireless technology to deliver network connectivity and communications for train systems and passengers. However, solution providers need to address several major challenges if they are to meet the needs of the rolling stock industry. This paper discusses how many of these challenges can be met through the use of an intelligent routing platform..........more
