Equipped with up to four 3G/4G modules, which can be bundled, Netmodule’s railway router’s total bandwidth can be extended to the needs of the intended applications. Especially with passenger entertainment applications, the increased total throughput generates a better user experience. The quad SIM feature and the WAN link manager offer 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 standard and 2 x 2MIMO beam forming technology. Available options include interfaces for CAN, EIA-232, EIA-485, Audio Line I/O, GSM-R, IBIS, and dead reckoning GNSS. The router fulfills the EN 50155 requirements. 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 block high priority data transfer.

The built-in SSD disk with up to 1-TiB storage keeps documents, pictures, audio, and video files as well as application specific web page content. A web server for web pages, WiFi captive portal software, and a media server for streaming audio, pictures, and videos is also included. The router software is based on an embedded Linux operating system and a 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 an application interface. Customer specific software extensions may be developed via an SDK.

Netmodule (Switzerland) also offers the similar NB2800 Media Vehicle with E-mark certification. It is the company’s latest vehicle router and enables passenger WiFi and entertainment as well as condition monitoring and remote management. With its CPU, the NB2800 achieves data rates up to 1 Gbit/s and enables Gigabit routing. Available extensions include interfaces for CAN.
