As part of a major refurbishment of over 200 high-speed trains in Germany, a leading telecommunications system integrator partnered with Moxa, a leading provider of industrial networking and computing solutions, to deploy customized AWK-5232-M12-RCC wireless dual radio APs with 802.11n Auto Carriage Connections technology.
This refurbishment added onboard passenger Wi-Fi through wireless hotspots that gives passengers onboard access to travel updates from the ground, email, and web video.
In order to provide wireless hotspots on train carriages, the onboard system must have a modern communication backbone. However, in a refurbishment project such as this one, there are rarely any spare wires available to establish Ethernet data links between train cars. This makes a wireless backbone the obvious solution that minimizes deployment cost and effort for train refurbishments.
However, during actual operations, it can be tedious to constantly configure wireless links between different carriages. A configuration-free setup in which wireless access points seamlessly connect carriages with secure point-to-point wireless links and avoids manual configuration errors would be a far more efficient solution.
To meet onboard space limitations, Moxa offered a customized flexible wireless solution which presented all the physical inputs on the front panel. For this project, two customized AWK-5232-M12-RCC dual-RF 802.11a/b/g/n wireless devices are mounted next to each other and linked via Ethernet. Two RF cards on this system establish the secure 5GHz point-to-point inter-carriage wireless link. The other two RF cards serve as 2.4GHz access points for passenger Wi-Fi. In addition, to increase the installation and maintenance efficiency of the inter-carriage wireless link, Moxa's proprietary Auto Carriage Connection (ACC) technology is used. ACC allows each unit to come with a single default configuration which does not ever need to be changed during operations.
