Objective

5G-PHOS aims to develop novel 5G broadband fronthaul architectures and evaluate them for Ultra-Dense and Hot-Spot areas exploiting the recent advances in optical technologies towards producing a powerful photonic integrated circuit technology toolkit. It aims to capitalize on novelties in InP transceiver, Triplex optical beamformers and multi-bitrate optical communications into next generation fronthaul in order to migrate from CPRI-based to integrated Fiber-Wireless packetized C-RAN fronthaul supporting mm-Wave massive MIMO communications.

Achievements

The 5G-PHOS project has made remarkable progress since its launch date as it has produced the first of its kind analog Fiber-Wireless (FiWi) Point-to-Multipoint (PtMP) fronthaul architecture, capable of supporting the target 5G New Radio fronthaul bandwidth, while at the same time alleviating the need to install fiber terminations at every Mobile Network Operator (MNO) Access Point site. In this way, 5G-PHOS transforms the current all-digital Point-to-Point fronthaul that necessitates direct and dedicated links from the centralized location to all remote locations, to a PtMP digital + analog converged FiWi fronthaul that addresses the problem of 5G NR densification since it allows for flexible wireless last-mile placement of the remote equipment in the area of service while maintaining compatibility with the eCPRI standard. By offering the aforementioned advantages, the 5G-PHOS solution becomes a very appealing proposal for both vendors and MNOs, since to the best of our knowledge it is the only solution that specifically targets to reduce the costs of 5G NR densification. Experimentally-wise, the project has recently succeeded in transmitting the world’s highest cumulative 5G optical-wireless transmission speed, by concurrently transmitting 6 millimeter-wave channels, each carrying up to 4 Gb/s of data by use of highly directional 60 GHz antennas (more info: www.5g-phos.eu). At the end of the project, 3 large-scale demonstrations will be presented in Athens, Thessaloniki and Turin where all the achievements of the program will be demonstrated in real load conditions and with real telecommunication equipment provided by COSMOTE, ORANGE and TIM operators.
