Poster: Multi-RAT Network Slicing in the Open RAN Era

While Open RAN harbors the potential to revolutionize cellular access networks, the absence of an open platform for use case prototyping and a near-exclusive focus on 5G SA have tempered its commercial appeal. With a view to addressing these limitations, this paper introduces a disaggregated O-RAN platform with a novel multi-RAT RAN slicing framework across LTE, 5G NSA, and 5G SA. A preliminary performance evaluation showcases promising results addressing key features related to end-user service quality and use case-specific adaptability.
