ITS DESIGN MAKES THE GATEWAY RESISTANT to vibrations and shocks and gives it tolerance to an extended temperature range. Applications include passenger Wifi, online passenger information, passenger counting, driver communication, emergency calls, remote control, condition monitoring, and data exchange in real time.

The data transfer from CAN and IP-based networks can be carried out via an integrated CAN port. In addition, an Ibis interface for connection with a computer-based operator system in the vehicle is optionally available. Features also include eight Ethernet interfaces (Neutrik RJ45), two of them with Gigabit transfer capability.

The multi mobile and Wifi router enables wireless Internet access via multiple UMTS (3G)- and/or LTE (4G)-modems and supports multipath routing. Its integrated load balancing distributes outgoing traffic to the wireless modems. Seamless switch-over from LTE to UMTS or GSM technology is provided by the implemented Mobile IP protocol. Multi-SIM functionality – the device integrates up to four SIM cards – and the WAN link manager guarantee connection availability by using multiple network providers. Additionally, a VoIP/GSM gateway for voice communication via Internet or GSM can be integrated. Thanks to its port-based subnetting feature, the gateway is able to separate different application networks logically, thus avoiding interferences and guaranteeing secure communication paths.

The router software is based on various components including an embedded Linux operating system and a communication protocol suite. The device is managed via web browser, command line, or SNMP. Users can configure it remotely via an application interface. Customer specific software extensions are accomplished via an SDK.
