Alternative Bearers for Rail – COLA Meeting 7th June 2021

The third important meeting between the X2Rail project consortium and the AB4Rail project partners was held on June 7, 2021. AB4Rail partners presented the latest advances on the procedure to assess the Alternative Bearers (ABs) in the rail sector to support train operations.

AB technologies related to Adaptable Communication System (ACS) will be evaluated in each rail scenario (such as station, metro, regional and main line) and for each ACS traffic class (such as critical data, critical video, critical voice and non-critical data).

The AB eligibility will consider the evaluation of both (i) the aggregate radio capacity (peak and average) and (ii) the latency, for each ACS traffic class. Furthermore, other specific criteria will be considered such as the impact on the existing infrastructure, the technology maturity, and coexistence issues.

Lars Bruehl (SMO) highlighted the need of investigating economic impacts of ABs. Also, Kerstin Keil (DB) suggested to consider 5G as a technology to compare with selected ABs, when applicable.

The next meeting will be on July 5, 2021!
