Smart city hardware is quietly turning modern cities into giant distributed computers. But what actually sits behind the AI cameras, IoT sensors, 5G networks and intelligent infrastructure?

In this episode of Silicon to Software, Imran Valiani breaks down the six physical hardware layers making smart cities possible—from sensors buried beneath roads to edge AI computers operating inside traffic cabinets.

We go beyond the apps and dashboards to examine the engineering underneath the smart city.

You'll discover:

• How IoT sensors monitor traffic, parking, air quality, water systems and urban infrastructure • Why LoRaWAN and NB-IoT make massive sensor deployments practical • How AI-powered cameras perform inference directly at the edge • Why edge computing matters when milliseconds count • How 5G, RedCap and fiber work together across urban networks • Why smart streetlights are becoming IoT infrastructure hubs • What IPC-6012 Class 3, conformal coating and environmental protection mean for outdoor PCB reliability • How city operations centers aggregate massive amounts of infrastructure data • Why OT cybersecurity requires a different threat model from enterprise IT • How Zero Trust, SBOM requirements and post-quantum cryptography are beginning to influence next-generation infrastructure

A modern smart city isn't simply "connected."

It's a distributed computing system.

Sensors become its inputs. Edge computers become local processors. Fiber and 5G become the communications fabric. Data centers become the aggregation layer.

And underneath all of it is physical hardware that has to survive years of heat, moisture, vibration, cybersecurity threats and continuous operation.
