Smart cities are connected cities, and they work in conjunction with everything from IoT sensors to open data collection and smart streetlights to provide better services and better communication.

Smart cities are no longer the wave of the future. They are here now and growing quickly as the Internet of Things (IoT) expands and impacts municipal services around the globe.

The smart city industry is projected to be a $400 billion market by 2020, with 600 cities worldwide. These cities are expected to generate 60% of the world's GDP by 2025, according to McKinsey research, as previously published in TechRepublic.
