Terahertz Technologies to Deliver Optical Network Quality of Experience in Wireless Systems Beyond 5G
Alexandros-Apostolos A. Boulogeorgos,Angeliki Alexiou,Thomas Merkle,Colja Schubert,Robert Elschner,Alexandros Katsiotis,Panagiotis Stavrianos,Dimitrios Kritharidis,Panteleimon-Konstantinos Chartsias,Joonas Kokkoniemi,Markku Juntti,Janne Lehtomaki,Antônio Lúcio Teixeira,Francisco Rodrigues +13 more
TL;DR: The basic system architecture for THz wireless links with bandwidths of more than 50 GHz into optical networks is discussed and the role of PBF is highlighted, which is required in order to overcome the propagation losses, as well as the physical layer and medium access control challenges.

Towards a Scaleable 5G Fronthaul: Analog Radio-over-Fiber and Space Division Multiplexing
Simon Rommel,Delphin Dodane,Evangelos Grivas,Bruno Cimoli,Jérôme Bourderionnet,Gilles Feugnet,Alvaro Morales,Evangelos Pikasis,Chris G. H. Roeloffzen,Paul van Dijk,Michail Katsikis,Konstantinos Ntontin,Dimitrios Kritharidis,Izabela Spaleniak,Paul Mitchell,Mykhaylo Dubov,Juliana Barros Carvalho,Idelfonso Tafur Monroy +17 more
TL;DR: The use of analog radio-over-fiber (ARoF) is proposed and demonstrated as a viable alternative which, combined with space division multiplexing in the optical distribution network as well as photonic integration of the required transceivers, shows a path to a scaleable fronthaul solution for 5G.
