Wireless communication is advancing, leading to 6G networks. These networks will reshape society with unprecedented connectivity and intelligence. 6G is key for future smart cities, integrating terahertz communication, ultra-low latency, and AI-driven networks. This will create hyper-connected cities where real-time data supports systems like autonomous vehicles, energy management, and public safety. 6G research shows its potential for ultra-reliable communication, immersive experiences like extended reality, and widespread sensing, crucial for smart city applications. However, challenges like technical issues, data privacy, and regulations need addressing. This chapter proposes a 6G-enabled smart city model using IoT, AI, and edge computing to improve urban operations. It explores dynamic network slicing, intelligent resource allocation, and edge AI processing to meet latency and bandwidth needs. The chapter concludes by emphasizing collaboration and strategic planning to overcome challenges, ensuring 6G technologies foster sustainable urban growth.
