6G mobile technology will revolutionize connectivity for smart cities by enabling real-time data analysis, traffic management, and emergency response applications through faster and more reliable connections. 6G is expected to support speeds in the terabit range, zero-distance connectivity, augmented and virtual reality applications, and more advanced Internet of Things sensors to monitor city infrastructure like energy use and air quality. The 6G network architecture will utilize technologies like geosynchronous orbital satellites, unmanned aerial vehicles, and high altitude platforms to connect cities through next-generation 11Gbps bandwidth and terabyte storage capabilities.
