The technology underpinning the development of smart cities includes the Internet of Things (IoT), big data analytics, and advanced communication networks. IoT devices, such as sensors and smart meters, collect real-time data to monitor and manage urban infrastructure efficiently. This data is analyzed to optimize resources like traffic flow, energy consumption, and waste management. Furthermore, 5G technology enhances connectivity and responsiveness in smart city applications. The integration of these technologies aims to improve sustainability, enhance public services, and create a more livable urban environment for residents.
