MARSAL aims to provide an evolved architecture towards Beyond 5G (B5G), offering unprecedented degrees of flexibility and closed-loop autonomy at all tiers of the infrastructure, and significantly improved Spectral Efficiency via Cell-Free Networking. The overall concept of the MARSAL project is structured over three main pillars that in turn highlight the core activities of the project:
- The network design pillar
Offers a combination of innovative cell-free and Hybrid Multiple Input Multiple Output technologies for the Radio Access Network (RAN) and Fronthaul domains, fully aligned with recent initiatives towards an Open RAN (O-RAN).
- The Elastic Edge Infrastructure pillar
Will support a fully Elastic Edge Cloud and dynamic slicing support for the wireless and optical domains, offering zero perceived latency to Multi-access Edge Computing (MEC) applications.
- The Network security pillar
Will focus on the security and privacy implications of multi-tenant infrastructures, offering a holistic framework for end users and tenants.
The overall architecture and the structure of the envisioned Beyond 5G (B5G) MARSAL is depicted in the generic schematic above, and includes all the main infrastructure elements that are deployed within MARSAL project. MARSAL adopts an evolved 3rd Generation Partnership Project (3GPP) Next Generation RAN (NG-RAN) which is extended with emerging Cell-Free technologies for network densification. Moreover, MARSAL contributes with innovations at the optical transport domain and significantly evolves the MEC system towards fully elastic Edge Computing. MARSAL will deploy a distributed Edge infrastructure with Data Centres (DCs) structured in 2 tiers, featuring Regional Edge and Radio Edge nodes. Radio Edge DCs will host the Network Functions of the (virtualized) RAN, which fully aligned with the O-RAN specifications.
