mmWave Onboard Rail Node for Data Offloading

Westermo’s mmWave solution is optimized for high-capacity data offloading in stationary and low-speed applications, providing multi-gigabit connectivity between trains and trackside infrastructure. The solution also supports continuous connectivity while the train is moving at speeds of up to 30 km/h.

The Oryx-7121 is designed and qualified for onboard deployment, offering extended service life and low maintenance requirements. The solution consists of three components: a train-top unit, a specially designed connection cable, and an in-train CPU. The compact Oryx-7121 is compliant with EN 50155 for onboard railway applications.

The Oryx-7121 onboard unit operates together with the Oryx-7122 trackside unit to establish a high-capacity mmWave link between the train and trackside infrastructure. Both units feature two radios operating together to provide an aggregated data throughput of approximately 2–4 Gbps per train, maintaining continuous connectivity while the train is moving.

Both the train and trackside units incorporate the RWM6050 dual-modem IC with HYDRA technology from Blu Wireless, together with two-sector electronically steered phased-array antennas operating in the unlicensed 60 GHz spectrum and a quad-core ARM network processor. The units provide flexible network and edge application configuration within a standard, secure Linux environment.

The Oryx-7121 also incorporates advanced cybersecurity capabilities. Wireless links are protected with AES-128 encryption in the standard configuration and AES-256 encryption in the extended-range configuration.
