Since 2011, the Smart City Expo World Congress has stood as the world’s largest and most influential platform for cities and urban innovation. Hosted annually in Barcelona, it brings together a powerful global ecosystem of leaders from major corporations, national governments, research institutions and strategic organizations that are actively shaping the next era of urban development.
In this first instalment of the Smart City series, we explore what truly defines a “smart city,” the systems and principles that make it work, and why people, not machines, must remain at its core. With the recent 2025 conference staging offering a vivid display of global innovation and practical implementation, Barcelona provided the perfect backdrop for examining both the tremendous promise and the profound responsibility involved in building the cities of tomorrow.

Cities are rapidly evolving from passive infrastructure into intelligent, adaptive systems. This shift from “smart” to “thinking” cities could redefine governance, opportunity, and daily life
- Cities are evolving into intelligent systems that learn and act autonomously, reshaping mobility, energy, health, and infrastructure.
- Urban AI raises risks related to governance, privacy, inequality, and resource use, making strong oversight and inclusion essential.
- Nations must invest in talent, environmental safeguards, and innovation to ensure intelligent cities expand opportunity rather than concentrate power.

From open data portals to speed cameras, practical digital tools are reshaping city services — and oversight needs to catch up.
- Despite its roots in corporate sales efforts, the lasting appeal of smart cities lies in their focus on efficiency, data-informed governance and better outcomes for residents, not flashy gadgets.
- As AI becomes embedded in government operations, experts emphasize the need for transparency to avoid reinforcing surveillance or inequality.
- True progress in smart cities depends less on acquiring new tools and more on coordination, long-term political commitment and ensuring residents experience tangible benefits from digital systems.
Smart cities started as marketing jargon to sell tech tools. Over the last 25 years, “smart city” has evolved into something quieter but more powerful.

In a world where cities are getting smarter every day, how they share data is more important than ever. Smart-city systems use sensors, cameras, traffic lights, and lots of digital signals to help us live safer, cleaner and smoother lives. But to work properly, they need strong links, both inside the city, and to far-away data centres overseas. That’s where smart-city connectivity becomes vital.
Local Access Meets Global Reach
Inside a city, data flows fast. Streetlights with sensors, traffic monitors, public WiFi and environmental alerts generate huge volumes of information. This is the local access side of smart-city connectivity. But many of the insights, AI analysis, cloud storage, backup, or heavy computing, happen beyond city borders. That means data must travel from edge and municipal networks to data centres abroad. To ensure resilient international access, cities must pair edge-computing infrastructure with reliable global links.

As the world commemorates World Cities’ Day 2025, under the theme “People-centred Smart Cities,” the United Nations emphasises the critical need to scale and upgrade urban areas to meet the demands of growing populations and to foster more liveable environments.
Since its inception in 2014, the World Cities Day has marked the culmination of Urban October, aiming to raise awareness about urbanisation trends, associated challenges, and visions for sustainable development. This day encourages international cooperation towards building equitable, prosperous, and inclusive cities that enhance residents’ quality of life.
