Everyone is aware of the current trends towards certain technological advancements, 5G being one of them. However, it is not the trend that is important for the mobility sector with regard to the next generation of radio technology, but rather the promise to move away from proprietary Wi-Fi or the more than 25-year-old GSM-R communication systems.

It is about enabling new business models and cost savings and building a foundation that the digitalisation of the railway can expand on through innovation.
