Nomad Digital
The Intelligent Journey Powered by Onboard Connectivity
This article first appeared in the Railway-News Magazine Issue 4 2023.
There is an ever-growing demand for connectivity in public transport, both from passengers and operationally, including passenger information systems (PIS) and CCTV, creating additional needs for logging and maintenance. This has generated a corresponding demand for ever higher bandwidth, whilst ensuring secure, continuous connectivity.
Nomad Connect – Best of Class Connectivity
Nomad Connect combines multiple links and technologies, so that high-throughput and continuous connectivity can be provided on board. For an optimal level of service or when operating between population areas, the traffic is aggregated and tunnelled over our Customer Data Centre (CDC) for uninterrupted service. For an urban project with good, continuous coverage, a solution without tunnel can suffice, thereby reducing the operational cost.
For the majority of projects, we utilise cellular connectivity. Our new range of Communication Control Units (CCU) provide full 5G and multi-SIM support. Nomad Digital’s entry-level router supports two 5G modems and is best suited to provide internet access in areas with good coverage. Nomad high-end routers can support up to 6 modems, multi-gigabit connectivity and can run a multi-media portal or additional services in parallel.
Cellular connectivity can be combined with other technologies such as mmWave, trackside radio or satellite. This allows a multi-gigabit link over the entire trajectory.
