DG-DCORE-DR01-MIMO - 5G Railway Router

The DCORE-DR01-MIMO is a powerful stand-alone high reliability 4x4 MIMO 5G Train EDGE Gateway Router with a dedicated LINUX application processor capable of independently executing Client Services. This DR01 router variant is completely fucntionally compatible with the DG-DCORE-DR01-R.

This device combines the functions of an EDGE gateway computer with a HW accelerated dedicated WRT router core, which directly manages the 5G modem. Separate processors are used for application software and the WRT Linux router to improve performance and enable easier software development. The application processor directly connects to the core router with an internal Ethernet interface. This enables independent upgrading of application layer software services without the need to touch the Layer 3 routing core software.

The figure below illustrates the DCORE-DR01-MIMO in a typical coach PIS modernisation solution.


The small footprint DCORE-DR01-MIMO is ideal for upgrade programs due to its small size and support for project specific firmware adaptations. Train location is based on an IMU supported high sensitivity ADR GNSS subsystem. The 5G modem is based on the latest Qualcomm SDX65 chipset, which supports UL and DL MIMO using n40 and n78 bands. Standard RJ45 connectors are used for the Ethernet interfaces.

The router features a soldered down GNSS subsystem with UDR support for installation cases where limited satellite coverage is available. The UDR based positioning can reliably navigate underground or in poor satellite signal conditions assisted by the IMU based sensor data.

Duragon can supply a suitable railway compliant antenna with 2x2 MIMO 5G and GNSS. Ina 4x4 MIMO solution two such antennas would be used.
