5G-PHOS
5G integrated Fiber-Wireless networks exploiting existing photonic technologies for high-density SDN-programmable network architectures
(9/2018 – 8/2021)

Aim: The development of novel 5G fronthaul architectures and their evaluation for ultra-dense and hotspot areas leveraging recent advances in optical technologies

COSMOTE participates in the European research project 5G-PHOS (http://www.5g-phos.eu/) which aims at developing novel 5G broadband fronthaul architectures and producing a powerful photonic integrated circuit technology toolkit that will exploit the recent advances in optical technologies enhancing Fiber-Wireless (FiWi) convergence and realizing cost-effective and energy-efficient 5G network solutions for high density use cases.

5G-PHOS capitalizes on novelties in InP transceiver, Triplex optical beamformers and multi-bitrate optical communications to migrate from CPRI-based to an integrated Fiber-Wireless (FiWi) packetized SDN-programmable 5G fronthaul that supports 64x64 MIMO antennas in the mm-wave band offering:

• Up to 400 Gb/s wireless peak data rate in ultra-dense networks, adopting optical Spatial-Division-Multiplexed solutions on top of  the emerging 25 Gb/s PON and
• Up to 100 Gb/s wireless peak data rate in hotspot areas, showcasing the benefits of WDM technology and packetized fronthauling in private C-RAN solutions.

Lab/testbed experiments and field trials will be conducted towards the evaluation of the project outcomes for dense, ultra-dense and hotspot areas.
COSMOTE is responsible for the Technical Coordination of the project and brings the mobile network operator's perspective and expertise towards the development and validation of a 5G solution suitable for high density use cases, while promoting the 5G-PHOS scope, objectives, innovations, results to the research and industry communities.

The project is co-funded by the EU through the Horizon 2020 Programme, within the scope of the 5G-PPP Phase 2 framework and will be running for 3 years; it is realized with the participation of 16 partners from 10 countries (Greece, Cyprus, Spain, Germany, France, Belgium, United Kingdom, Denmark, Netherlands, Italy and Israel) and coordinated by the Aristotle University of Thessaloniki.
