5 Shades of Cooperation: Spectrum Sharing in the Upper-Mid Band
Alberto Ceresoli, Marco Mezzavilla, Ilario Filippini +1
Spectrum exclusively licensed to each mobile network operator (MNO) is scarce, and assigning it in fixed, frequency-orthogonal blocks leaves much of it idle under heterogeneous, ti…
Toward Mobile and Converged Backhaul: The Promise of Wireless Access and Backhaul
Chiara Rubaltelli, Marcello Morini, Eugenio Moro +2
Wireless Access and Backhaul (WAB) is emerging as a key enabler for flexible and cost-efficient 5G deployments, offering a modular architecture that decouples access and backhaul w…
Predicting Networks Before They Happen: Experimentation on a Real-Time V2X Digital Twin
Roberto Pegurri, Habu Shintaro, Francesco Linsalata +6
Emerging safety-critical Vehicle-to-Everything (V2X) applications require networks to proactively adapt to rapid environmental changes rather than merely reacting to them. While Ne…
Towards Smart Fronthauling Management: Experimental Insights from a 5G Testbed
Marcello Morini, Eugenio Moro, Ilario Filippini +3
The fronthaul connection is a key component of Centralized RAN (C-RAN) architectures, consistently required to handle high capacity demands. However, this critical feature is at ri…
Shaping Radio Access to Match Variable Wireless Fronthaul Quality in Next-Generation Networks
Marcello Morini, Eugenio Moro, Ilario Filippini +2
The emergence of Centralized-RAN (C-RAN) has revolutionized mobile network infrastructure, offering streamlined cell-site engineering and enhanced network management capabilities.…
Exploring Upper-6GHz and mmWave in Real-World 5G Networks: A Direct on-Field Comparison
Marcello Morini, Eugenio Moro, Ilario Filippini +2
The spectrum crunch challenge poses a vital threat to the progress of cellular networks and recently prompted the inclusion of millimeter wave (mmWave) and Upper 6GHz (U6G) in the…
ScalO-RAN: Energy-aware Network Intelligence Scaling in Open RAN
Stefano Maxenti, Salvatore D'Oro, Leonardo Bonati +3
Network virtualization, software-defined infrastructure, and orchestration are pivotal elements in contemporary networks, yielding new vectors for optimization and novel capabiliti…
An Open RAN Framework for the Dynamic Control of 5G Service Level Agreements
Eugenio Moro, Michele Polese, Antonio Capone +1
The heterogeneity of use cases that next-generation wireless systems need to support calls for flexible and programmable networks that can autonomously adapt to the application req…
