EN 50155 Certified LTE/UMTS Router with WiFi 802.11abgn and GPS



The NB3700 CompactRail provides wireless Internet access on board. The compact device integrates a WiFi access point and further interfaces for various application like remote access, data acquisition and passenger information.

The NB3700 is the preferred communication device for railway and public transport applications. Thanks to its unique port-based subnetting feature, the NB3700 is able to separate different application networks, thus avoiding interferences and guaranteeing dedicated communication paths. Quality of Service support allows to prioritizing the traffic to avoid that less important tasks are blocking high priority data. The NB3700, operating as communication gateway of the vehicle, enables access to remote stations for any kinds of applications in the Internet, but also to Intranet sites which can be connected via its powerful VPN protocol suite. Multiple devices can directly be attached to the NB3700 by using the integrated 5 port Ethernet switch.

Equipped with multiple LTE/UMTS modules the total bandwidth can be extended to the needs of the applications. Especially in passenger Wi-Fi applications the increased total throughput gives a better user experience.

The router software is based on well proven components including an embedded Linux operating system and standard communication protocols. The device is administrated via web browser or command line. Selfprovisioning for new software or new configuration is possible. The device can be configured remotely by customer programs via a powerful application interface.

The router is qualified for operating under harsh environmental conditions defined by EN 50155, supporting the temperature range TX (-40°C to +70°C, +85°C for 15 minutes). The dual SIM feature and the sophisticated WAN link manager are offering high availability of network connections between multiple network providers.
The device is now also available with extended input voltage (72, 96, 110V).
