Low latency and immediate setup are highly demanded in most of the critical applications. Voice calls shall be supported, including user-to-user and multi-user. Narrow 6 band systems seem to be sufficient to support voice and data in critical applications. 6 New future railway critical applications are being considered nowadays and could change this conclusion about narrow band systems and their ability to support the complete set of voice/data critical apps. For example, the transmission of a real-time video for ATO purposes is being discussed at present. If this application (or a similar one) is finally confirmed, this assumption will not be true. However, it is interesting to point out that in other fields (such as the RPAS – Remotely Piloted Aircraft System) similar discussions have been addressed, and finally video applications have been discarded. In fact, video image processing is expected to be eventually performed on-board (thus avoiding the transmission of large amount of data through the return channel).

Final Report Two-way communications (i.e. 50/50 symmetry) are required for most of the critical applications. These conclusions are taken into account in the parameters and criteria identification process (detailed in section §5), since they represent a key input for this process Doc.Nº: SRAIL-FNR-010-IND Edit./Rev.: 1/1 Date: 16/02/2017 Page 45 of 285
