Wireless-Optical Network Convergence: Enabling the 5G Architecture to Support Operational and End-User Services
Anna Tzanakaki,Markos P. Anastasopoulos,Ignacio Berberana,Dimitris Syrivelis,Paris Flegkas,Thanasis Korakis,Daniel Camps Mur,Ilker Demirkol,Jesus Gutierrez,Eckhard Grass,Wei Qing,Emmanouil Pateromichelakis,Nikola Vucic,Albrecht Fehske,Michael Grieger,Michael Eiselt,Jens Bartelt,Gerhard Fettweis,G. Lyberopoulos,Eleni Theodoropoulou,Dimitra Simeonidou +20 more
TL;DR: A converged 5G network infrastructure and an overarching architecture to jointly support operational network and end-user services, proposed by the EU 5G PPP project 5G-XHaul are presented.
Journal ArticleDOI
5G transport network requirements for the next generation fronthaul interface
Jens Bartelt,Nikola Vucic,Daniel Camps-Mur,Eduard Garcia-Villegas,Ilker Demirkol,Albrecht Fehske,Michael Grieger,Anna Tzanakaki,Jesus Gutierrez,Eckhard Grass,G. Lyberopoulos,Gerhard Fettweis +11 more
TL;DR: This work analyzes the impact that future RAN technologies will have on the transport network and on the design of the next generation fronthaul interface, and derives both per-cell and aggregated data rate requirements for 5G transport networks.
Proceedings ArticleDOI
5G infrastructures supporting end-user and operational services: The 5G-XHaul architectural perspective
Anna Tzanakaki,Markos P. Anastasopoulos,Dimitra Simeonidou,Ignacio Berberana,Dimitris Syrivelis,Thanasis Korakis,Paris Flegkas,Daniel Camps Mur,Ilker Demirkol,Jesus Gutierrez,Eckhard Grass,Wei Qing,Emmanouil Pateromichelakis,Albrecht Fehske,Michael Grieger,Michael Eiselt,Jens Bartelt,G. Lyberopoulos,Eleni Theodoropoulou +18 more
TL;DR: This work proposes an optical-wireless 5G infrastructure offering converged fronthauling/backhauling functions to support both operational and end-user cloud services that can offer significant energy savings but there is a clear trade-off between overall energy consumption and service delay.
Journal ArticleDOI
5G-XHaul: a converged optical and wireless solution for 5G transport networks
Jesus Gutierrez,Nebojsa Maletic,Daniel Camps-Mur,Eduard Garcia,Ignacio Berberana,Markos P. Anastasopoulos,Anna Tzanakaki,Vaia Kalokidou,Paris Flegkas,Dimitris Syrivelis,Thanasis Korakis,Peter Legg,Dusan Markovic,G. Lyberopoulos,Jens Bartelt,Jay Kant Chaudhary,Michael Grieger,Nikola Vucic,Jim Zou,Eckhard Grass +19 more
TL;DR: 5G‐XHaul studies the trade‐offs involving fully or partially converged backhaul and fronthaul functions, with the aim of maximising the associated sharing benefits, improving efficiency in resource utilisation and providing measurable benefits in terms of overall cost, scalability and sustainability.
Journal ArticleDOI
Early experiences and lessons learned from femtocells
TL;DR: In this article, the experience from an extensive study and trials of early (pre-standard) femtocell solutions that were available in the 2007-2008 timeframe are presented.
