Summary of the most important features for selected ABs

These data summarizes the relevant findings and the identified limitations (in terms of "Category", "Technology", "Properties", "Limitation", and "Applicability to railway"), coming from the overview of different Alternative Bearers (ABs), carried out in deliverable D21 (AB4Rail project, www.ab4rail.eu).
The results have provided an overview of several technologies, each of them showing specific characteristics. The heterogeneous nature of different ABs allows to provide a plethora of available communication technologies to be potentially used by the Adaptable Communication System (ACS) for different railway scenarios. All the selected ABs provide the IP interconnection feature since they are Integrated within OSI reference model.
In this way, it collects the planned objectives of deliverable D2.1, expressed as a technological overview of selected ABs, as possible candidates coexisting with Traditional Bearers (TBs) for supporting railway applications.
