Special Session 3
Wireless and Optical Technologies for Systems Beyond 5G
- Wednesday, 14 June 2017, 11:00-12:30, Room Radisson Blu Kiikeli
- Session Chair: Angeliki Alexiou (Piraeus University, Greece), Raul Munoz (CTTC, Spain)
Assuming success, 5G will not just introduce a new way of thinking in wireless networks design and optimization, but a new era, where ‘Wireless Connectivity as a Utility’ will completely transform the way people, things and (any) application devices communicate, store and process information. 5G is also about an end-to-end converged transport network and cloud infrastructure, and particularly optical networks are key to meet the transport requirements of the mobile x-haul (fronthaul/ midhaul/ backhaul) in terms of high-bandwidth, low-latency, jitter and synchronization. As speed (data rate), data volume, distance, agility (latency), security and reliability become ‘non-issues’, ‘infinite’ capacity and unlimited connectivity initiate an ecosystem paradigm shift, according to which the optical network and cloud infrastructure as a whole is always available, scalable, and functioning ‘in the background’, whereas wireless access is ubiquitous and technology agnostic (independent). By achieving these ambitious targets, 5G will open up novel, green field research directions that only under the prism of the new thinking on wireless and optical integration can unleash their true potential.
Although 5G seems more than willing to embrace several game changing design principles, such as virtualization and softwarization, in order to enhance scalability, flexibility and efficient resources utilisation, it can be easily understood that fundamental performance limitations related to available bandwidth, transmission and processing delay and cost and energy consumption still define the envelope. To break these technological barriers networks beyond 5G will need to bring little explored wireless & optical resources and technologies to validation and exploitation by directing research towards de-risking technological concepts, components, architectures and systems concepts.
This Special Session will host contributions that address the design, analysis and assessment of innovative theoretical models, information theory and signal processing approaches, resource and interference management strategies and overall network architecture for systems beyond 5G.
The following research directions are envisioned to be addressed:
- Wireless massification system concept: heterogeneous ultra-dense networks and massive MIMO
- Wireless access via proximal links: D2D, M2M, …
- mmWave and THz communications
- Extreme resources sharing and commoditisation
- Radio over fiber for high-density distributed antenna systems
- Converged disaggregated optical x-haul networks (fixed and mobile users)
- Integration of edge cloud in optical access network for mobile services
