Duagon G239 5G wireless high-speed interface board

Designed for communication in embedded and harsh environments like rail, the Duagon G239 is a rugged CompactPCI Serial carrier board that provides 5G mobile communication features to 19″ systems. With a powerful CPU, the interface board features various application possibilities, such as Internet-on-board, general back-office communication, live CCTV to control centres or predictive maintenance. It is designed for -40 to +85°C operating temperature.

To use the wireless functionality, the interface board has three slots: two M.2 slots for 5G and one PCI Express Mini Card slot for WLAN. For 5G mobile communication the board is equipped with eight QLS antenna connectors (four connectors for each M.2 card) as well as up to three QLS antenna connectors for WLAN functionality. A high-precision GNSS receiver is also available for track accurate locating, as an example.

In the train communication system architecture, the interface board is typically located at the front end where it communicates directly with a cellular network. It features eight microSIM card slots to, eg, save roaming costs when operating trains across borders, have as much data volume available as possible (by switching to the next SIM card when the volume is used up) or to optimise the connection by choosing the provider with the best network coverage in the region the train is passing.

A user-friendly software tool is also included for interacting with the interface board. The user is thereby able to remotely control which microSIM cards are connected to the modems and can remote power reset each modem. Based on the CompactPCI Serial standard, the board features high-speed serial interfaces and comes with a conformal coating to facilitate operation in harsh and mobile environments. Additional long-term availability of the devices also provides an extended product life.
