City managers today are walking a high-wire. On one side, they are expected to tackle global crises like climate change and geopolitical instability. On the other, they face the daily “grind” of urban life: traffic congestion, housing shortages, and shrinking municipal budgets.
Layer on increasing safety concerns – from traffic accidents to public security – and the mandate becomes clear: Cities must protect citizens’ quality of life while aggressively while preventing environmental degradation and safeguarding key resources like energy and water.
IoT as the turning point
The advancement of IoT technologies has opened up entirely new possibilities for cities and moved past its experimental phase. IoT is now a key enabler of essential urban services such as street lighting, mobility and parking management, city surveillance, and more – providing the data-driven backbone cities need to stay resilient.
According to the latest report “Smart Cities: Connected Public Spaces” by Berg Insight, IoT technologies are experiencing a massive scaling:
- The global installed base of smart streetlights has already surpassed 27.9 million units.
- That number is projected to nearly triple to 74.5 million by 2029.
- Europe currently leads with 42% of total installations and North America is the second largest market, but the Middle East and Asia-Pacific are the ones to watch since showing the fastest growth, fuelled by ambitious top-down initiatives and rapid urbanisation.
From “cool” to “tangible outcome“
The industry is undergoing a fundamental shift in mindset. William Ankreus, IoT analyst at Berg Insight, explains: “Cities and municipalities are now prioritising ROI, operational savings and service quality over technology-led experimentation, accelerating the adoption of digital solutions that deliver tangible outcomes”.
Market conditions tend to favor large-scale smart city deployments. Whether it’s reducing energy bills through dimmable lighting or cutting carbon emissions via smarter parking management, the focus is firmly on the bottom line.
The last hurdle: Breaking the silos
Despite this progress, a major roadblock remains. Cities are still held back by a certain tendency to continue to manage services as separate silos – this means, deploying different networks to connect lighting devices, parking sensors, etc. and different platforms to monitor and control each application. This creates a fragmented environment that is expensive to maintain and very difficult to scale.
The greatest opportunity for 2026 and the years to come is interoperability. By choosing standards-based systems and open data models, cities can ensure their devices and platforms finally speak the same language.
The smart city market has reached maturity. The technology is ready, the ROI is proven, and the scale is there. To truly make urban living better, we must move beyond isolated applications and toward truly integrated urban ecosystems.
