Smart cities are no longer a utopian dream of the future. Thanks to a slew of innovative and game-changing technologies, they are already active and growing quickly. Smart cities could be described as the junction between three main areas, namely digital transformation, environmental sustainability and economic performance. They can be described as a framework made up of connected technologies designed to address the challenges of rapid urbanisation and promote more sustainable, smarter practices. And the more urbanisation soars, standards of living sustainability become more than pipe dreams, but rather calls for action.
