Out of Sight, but Essential: Networks, Sensors and Hidden Infrastructure

Most of what makes a smart city work isn’t visible. It sits in the background: networks, sensors, data centers, and devices quietly enabling all aspects of urban life. As cities rely more on real-time data and AI, this underlying infrastructure is under growing pressure to deliver faster, more reliable performance. That shift is driving innovation, while making issues such as cybersecurity, long-term maintenance, and the resilience of critical infrastructure in the face of disruptions and emerging threats increasingly important. Getting this foundation right is key to keeping urban systems running smoothly, securely, and at scale.
