The Flexi-DAS project, where AWTG is the project Lead, a collaboration between UK and South Korean partners, successfully concluded and achieved its key objectives in revolutionising Distributed Antenna Systems (DAS). We proudly highlight the integration of cutting-edge technologies, including Flex-5G Open RAN Mobile Private Networks (MPNs) and Reconfigurable Intelligent Surfaces (RIS), as major advancements that underscore our commitment to innovation.
AWTG, as the project lead, achieved a notable milestone by developing a flexible interface that enables seamless communication between DAS and Flex-5G Open RAN MPNs, enhancing interoperability and adaptability across platforms. Additionally, AWTG showcased an AI-driven energy efficiency software that optimises DAS antenna performance based on real-time traffic analytics. This innovation reduces energy consumption while enhancing data throughput. The successful integration of the DAS management system with a centralised network management platform further streamlined operational workflows, provided real-time end-to-end monitoring system , and enhanced diagnostics capabilities.
The University of Surrey (UoS) contributed to the project’s advancements in improving network coverage and data throughput, particularly in underserved regions, through the implementation of RIS and adaptive beamforming.
Lime introduced a unique plug-and-play 5G Mobile Private Network (MPN) solution utilising their Software Defined Radio (SDR) technology on commodity hardware and General Purpose Processors (GPPs). This versatile solution is customisable in frequency, power output, and adaptable to diverse applications and use cases. Lime’s open-source SDR modules, have fostered significant engagement and contributions, driving innovation within the Lime SDR ecosystem.
Sanaz Soltani, Security Technical Lead of AWTG and Project Manager of Flexi-DAS project shares
“The successful completion of the Flexi-DAS project marks a groundbreaking advancement in revolutionising DAS through the seamless integration of O-RAN Mobile MPNs and RIS. The development of a flexible interface that enables DAS system to communicate effortlessly with MPNs represents a significant milestone in our journey. By prioritising RIS, we effectively improving coverage challenges in underserved areas. Furthermore, our AI-driven energy efficiency software, which intelligently adapts to real-time network traffic, is essential for optimising performance while significantly reducing energy consumption. With the entire system managed through an end-to-end centralised monitoring system, we are setting new standards for operational efficiency and redefining connectivity within the 5G telecommunications , thus opening a wealth of opportunities for future contributions to 6G technology.”
Looking ahead, the closing event sparked engaging discussions about future collaborations, unveiling numerous opportunities for shaping the future of telecommunications. The completion of the Flexi-DAS project does not signify an end but rather a gateway to continued innovation and partnership in the industry. The project’s success not only highlights the potential for further advancements but also sets the stage for future endeavours aimed at transforming the global telecommunications landscape.
