The rapid advancements in 5G technologies are setting the stage for the evolution toward 6G, which promises to revolutionize connectivity, intelligence, and automation across various sectors. This paper explores the role of Artificial Intelligence (AI) in bridging the capabilities of 5G with the forthcoming 6G ecosystem, emphasizing the seamless integration of AI-driven systems to enhance network efficiency, performance, and decision-making. By analyzing the synergies between AI and next-generation wireless technologies, this study identifies key areas where AI can optimize spectrum management, network traffic, energy consumption, and security protocols. Furthermore, we discuss the potential challenges and opportunities presented by AI in shaping a hyper-connected world, where both virtual and physical environments are intricately interwoven. The paper offers a comprehensive roadmap for future research and practical implementations in preparing for a transformative 6G landscape. Series of simulation models and comparisons between 5G and 6G are illustrated and presented to showcase the expected performance improvements in key areas. A series of network-level simulation models—including throughput, latency, and energy efficiency analyses—are illustrated and presented to showcase the expected performance improvements in key areas as 5G evolves into 6G.
