ORANSight-2.0: Foundational LLMs for O-RAN

IEEE Transactions on Machine Learning in Communications and Networking
Despite the transformative impact of Large Language Models (LLMs) across critical domains such as healthcare, customer service, and business marketing, their integration into Open Radio Access Networks (O-RAN) remains limited. This gap is primarily due to the absence of domain-specific foundational models, with existing solutions often relying on ...
