5G-VICTORI: Future Railway Communications Requirements Driving 5G Deployments in Railways

Part 1: 6th Workshop on “5G – Putting Intelligence to the Network Edge” (5G-PINE 2021)International audienceThe complete transformation of the ICT domain driven by 5G network principles and capabilities, will impact significantly the path towards digitalization of many vertical industries, with modern railway transportations being one of them. In this context, Future Railway Mobile Communication System (FRMCS) service requirements and system principles are very well mapped to 5G service and network concepts associated with network performance, technology neutrality at various levels as well as network planning and deployment options. However, the flexibility of 5G networks implies that concepts are pinned down to deployment paradigms so that afore assertions are proved. The 5G-PPP project 5G-VICTORI aims at delivering a complete 5G solution suitable for railway environments and FRMCS services, along with experimentation deployments for testing and evaluation in operational railway environments. This paper discusses the service Key Performance Indicators (KPIs) and technical requirements and provides an overview of the proposed experimental deployment in an operational railway environment in the area of Patras, Greece

Terahertz technologies to deliver optical network quality of experience in wireless systems beyond 5G

Abstract This article discusses the basic system architecture for THz wireless links with bandwidths of more than 50 GHz into optical networks. New design principles and breakthrough technologies are required in order to demonstrate terabit- per-second data rates at near zero latency using the proposed system concept. Specifically, we present the concept of designing the baseband signal processing for both the optical and wireless links and using an E2E error correction approach for the combined link. We provide two possible electro-optical baseband interface architectures, namely transparent optical-link and digital- link architectures, which are currently under investigation. THz wireless link requirements are given as well as the main principles and research directions for the development of a new generation of transceiver front-ends that will be capable of operating at ultra-high spectral efficiency by employing higher-order modulation schemes. Moreover, we discuss the need for developing a novel THz network information theory framework, which will take into account the channel characteristics and the nature of interference in the THz band. Finally, we highlight the role of PBF, which is required in order to overcome the propagation losses, as well as the physical layer and medium access control challenges
