A smart city is an urban community that uses information and communication technologies (ICTs) to improve the quality of life of its citizens, optimise urban operations and promote sustainability. These smart cities integrate interconnected systems, sensors and digital platforms to collect and analyse data in real time, facilitating more informed decision-making and the efficient management of resources.

The characteristics of a smart city may include the implementation of smart grids for energy distribution, intelligent transport systems, efficient waste management, solutions for improving public safety, optimised public services thanks to connectivity, and intelligent use of information technologies to facilitate citizen participation.

The overall aim of a smart city is to optimise urban infrastructure, promote environmental sustainability, increase the efficiency of public services and improve the quality of life of its inhabitants by using innovative technologies and data to solve complex urban challenges.
