With its outstanding routing performance, the MediaRail enables next generation passenger WiFi, passenger information, digital signage and multimedia applications. The performant CPU achieves data rates up to 1Gbit/s via the Gigabit Ethernet ports to process data from the train network backbone.
The built-in SSD disk with up to 1TB storage keeps documents, pictures, audio, and video files as well as application specific web page content. A powerful Web server for own web pages, WiFi captive portal software and a media server for streaming audio, pictures and videos is also included.
Equipped with up to four LTE Advanced (Cat. 6) modules which can be bundled, the total bandwidth can be extended to the needs of the intended applications. Especially with passenger entertainment applications, the increased total throughput generates a great user experience. The quad SIM feature and the sophisticated WAN link manager are offering load balancing to achieve maximum connection availability using multiple network providers.The in-vehicle WiFi coverage is enhanced by providing up to two WiFi access points with latest IEEE 802.11ac 2x2 MIMO standard.
Thanks to its port-based subnetting feature, the NB3800 is able to separate different application networks, thus avoiding interferences and guaranteeing dedicated communication paths. Quality of Service support allows prioritizing the traffic to avoid that less important tasks are blocking high priority data transfer.
Available options include interfaces for CAN, RS-232, RS-485, Audio Line In/Out, GSM-R, IBIS and dead reckoning GNSS.
The router software is based on well proven components including an embedded Linux operating system and a powerful communication protocol suite. The device is managed via web browser, command line interpreter or SNMP. Self-provisioning for new software or new configuration is possible. The device can be configured remotely by customer programs via a powerful application interface. Customer specific software extensions may be developed via a sophisticated SDK.
The router is qualified for operating under harsh environmental conditions defined by EN50155 and fulfills fire safety requirements by EN45545.
