About CELTIC-NEXT
CELTIC-NEXT is the ICT Cluster within the EUREKA framework, specifically concentrating on Next-Generation Communications for the Digital Society. It is an inclusive community, boasting over 11,500 members from diverse backgrounds – big industry players, innovative SMEs, and academic/research institutions.
The projects are financed through a blend of public and private funding, fostering international research and development collaboration.
The RAI-6GREEN Project
The RAI-6GREEN, Robust and AI Native 6G for Green Networks, a CELTIC-NEXT project led by KTH (Royal Institute of Technology, Sweden) includes partners from Sweden, France, Hungary, Portugal and Turkey. RAI-6GREEN runs from January 2024 to June 2027.
The Global 5G Challenge
Globally, 5G deployment is rapidly increasing. While 5G technology offers more energy-efficient data transfer compared to legacy networks, the surge in data volumes leads to significantly higher overall energy consumption. This is a central issue addressed by the RAI-6Green project.
The increasing use of 5G networks for industrial and sensitive applications necessitates higher resilience. However, this creates a trade-off with energy efficiency, as ensuring network resilience against variable channel conditions, link failures, and disasters demands additional resources. The RAI-6Green project addresses this trade-off, which is inherent in the current cellular network architecture that offers limited elasticity due to fixed coverage and deployment.
Architectural and Efficiency Limitations
In addition to this tradeoff, the current cloud-centric data processing and storage architecture is an obstacle against both resiliency and energy-efficiency, as the need for sending data from devices to a far data centre results in a vulnerability against any intermediate link failure, and incurs high energy costs on the full path.
Project Objectives
The main goal of the RAI-6Green project is to achieve an improvement of about 30-40% of the end-to-end energy efficiency compared to current networks. This target is very challenging but possible considering results obtained by IT industries for operating data centers (in cooling for example) and access networks (e.g. resources optimization) for instance. These network segments are the most energy consuming parts of the IT infrastructure.
How Maven is Contributing
Maven Wireless provides a digital DAS platform for in-building and tunnel wireless coverage, supporting multiple operators and technologies. The unique Maven digital DAS platform enables energy saving by consolidating public 4G, public 5G, and private 5G networks onto a unified infrastructure, avoiding duplication of energy consuming network elements.
Scalable resiliency in a building is achievable with the Maven digital DAS platform by feeding an indoor venue with signals from different base stations and deploying in-building coverage based on a fully redundant fiber network.
