The advent of 5G technology marks a transformative era for smart tourism, enabling ultra-fast connectivity, immersive digital experiences, real-time interaction, and data-driven service personalization. This research article explores how 5G reshapes tourist experiences through enhanced mobile applications, augmented reality (AR), virtual reality (VR), Internet of Things (IoT), AI-driven personalization, autonomous mobility, and smart city infrastructure. Using academic literature, case studies, and hypothetical data models, the study demonstrates that 5G significantly improves destination management, customer satisfaction, operational efficiency, and real-time experience delivery. However, challenges such as infrastructure cost, cybersecurity risks, and digital inequality remain crucial considerations.
