As urban populations continue to grow, the concept of smart cities has become a central focus for governments, urban planners, and technology innovators worldwide. Smart cities integrate information and communication technology (ICT) to improve the quality of urban life, optimize resource management, and enhance citizen services. One of the key enablers of these developments is the evolution of mobile communication technology. While 5G has already transformed connectivity, 6G technology promises to take smart cities to a new level with ultra-fast, low-latency, and highly reliable connectivity.
