EWOC Enabling Virtualized Wireless and Optical Coexistence for 5G and Beyond

Summary

EWOC project aims at developing a novel converged optical wireless network solution relying on a flexible, virtualizable infrastructure, required for full resource optimisation beyond 5G (B5G) requirements. Fundamental innovation will be sought through merging of the enabling concepts of optical layer virtualization, high frequency mm-wave transmission, multiple antenna technology, cell densification, terra-over-fiber (ToF) based femtocell connectivity and cloud radio access network (C- RAN) architecture. EWOC will aim at high capacity, low latency communications (40-90 GHz frequency), providing the basis for a 50-fold improvement over the 5G baseline. This necessitates development of novel, femto-cell technology, and seamless coexistence with first round legacy deployment. Such scenario also requires novel channel models and simulation methodologies to attain the desired trade-off between coverage, throughput and densification limits. EWOC will rely on fiber-optic deployment towards ToF connectivity, as an “added on feature” for the C-RAN architecture supporting resource management of versatile services with varying demands. Scenario compliant optical fronthaul virtualisation techniques, designed to provide cost effective beyond state-of-the-art resource optimisation, will be pursued through novel optical transceiver schemes and software defined network-based digital signal processing techniques. Research and training
disciplines will serve as building blocks towards the scientific and socio-economic goals of increased capacity, coverage, flexibility, spectral efficiency, cost effectiveness, vendor agnosticism, and upgradability. EWOC provides a framework for promotion of such interdisciplinary innovation, with strong interoperability of models and methodologies from different disciplines. As such, EWOC training network is designed to foster opportunities for scientific and professional growth of ESRs from both topical and inter-disciplinary standpoints.
