How Electronics Manufacturing Supports the Growth of Smart Cities and Connected Vehicles
Smart cities and connected vehicles are usually talked about in terms of software, data, and AI. But behind every “smart” application is a lot of very real hardware: circuit boards, sensors, communication modules, cameras, and power electronics that have to work reliably in tough environments and at scale.
That’s where electronics manufacturing comes in.
Recent research on smart cities and connected vehicles shows just how quickly this ecosystem is expanding. Global smart-city initiatives now rely heavily on IoT devices for traffic management, public safety, energy optimization, and predictive maintenance. At the same time, the automotive electronics market is expected to grow from roughly USD 315B in 2024 to more than USD 560B by 2033, driven by connected, electrified, and automated vehicles.
Both trends depend on a common foundation: high-quality electronics manufacturing.
Smart Cities Run on Electronics
Modern smart-city projects are built on dense networks of connected devices:
- Sensors embedded in roads, bridges, and intersections
- Intelligent traffic controllers and smart signals
- Environmental and energy monitoring systems
- Public safety cameras and connected emergency systems
These systems rely on advanced PCB assemblies (PCBAs) that integrate sensors, power management, wireless connectivity (Wi-Fi, LTE/5G, LPWAN), and increasingly AI accelerators at the edge. Advanced PCBAs are already transforming intelligent traffic management improving safety, reducing congestion, and lowering emissions.
For electronics manufacturers, this means:
- Building boards that can handle temperature swings, vibration, moisture, dust, and electrical noise in outdoor enclosures
- Designing for long lifetimes and easy serviceability, since much of this equipment is installed in hard-to-reach locations
- Ensuring secure connectivity and updatable firmware so devices can stay in the field for years
Connected Vehicles Rely on the Same Manufacturing Backbone
Connected vehicles extend the smart-city network onto the road. They integrate dozens of electronic control units and hundreds of sensors including cameras, radar, lidar, GNSS, inertial sensors, and V2X modules to support ADAS, infotainment, predictive maintenance, and vehicle-to-everything (V2X) communication.
Studies on connected and automated vehicles emphasize that reliable electronics are a prerequisite for safety and performance: from telematics and over-the-air update modules to power electronics for EVs and high-bandwidth in-vehicle networking.
Electronics manufacturing supports this in several ways:
- Automotive-grade PCBAs for ADAS, cameras, radar, and domain controllers
- Ruggedization and testing for shock, vibration, humidity, and temperature extremes
- Traceability and compliance with automotive quality and safety standards
- Scalable production to support growing volumes as connected features become standard across more vehicle segments
As cities roll out V2X infrastructure that covers roadside units, smart signals, and sensor-rich intersections, electronics manufacturers become the common link between vehicle and infrastructure. AI-enabled PCBs and RF front-ends help make V2X communication faster and more reliable, improving safety and traffic flow.
Smart Factories Building Smart Mobility
The same IoT technologies that power smart cities are also reshaping electronics manufacturing itself. Recent work on “smart infrastructure and manufacturing” highlights how connected production lines, in-line sensors, and real-time analytics improve quality, traceability, and responsiveness.
For OEMs in the smart-city and automotive space, partnering with an EMS provider that runs a data-driven factory brings tangible benefits:
- Better process control and early detection of defects
- Real-time material and WIP visibility to manage complex builds
- Faster response to engineering changes as software and hardware co-evolve
- Documented process data that supports safety, compliance, and audits
Leading automotive and mobility manufacturers are already investing in AI-enabled, highly automated plants to keep up with the complexity of connected vehicles. Electronics manufacturers that adopt similar approaches are well positioned to support next-generation mobility programs.
What to Look For in an Electronics Manufacturing Partner
For companies developing smart-city infrastructure or connected-vehicle platforms, the choice of manufacturing partner is strategic. Some capabilities to look for:
- High-mix, complex manufacturing experience
Smart-city and automotive electronics often involve complex, multi-board assemblies, diverse product variants, and frequent design updates. A Tier-1 capable EMS partner with strong NPI and DFM support can help you ramp quickly without sacrificing quality. - Automotive and industrial quality mindset
Look for robust quality systems, traceability, and proven experience with long-life, safety-critical products. - Design and engineering collaboration
Early collaboration on PCB layout, component selection, thermal management, and test strategy can significantly improve reliability and cost over the product lifecycle. - Proactive supply-chain management
Smart-city and automotive programs often rely on long-lead, specialized components. A strong EMS partner monitors BOM health, identifies at-risk parts, and suggests alternates before they become a problem. - Support for connectivity and edge intelligence
From RF design considerations to secure firmware loading and functional testing, manufacturing needs to be aligned with your connectivity and cybersecurity strategy.
What’s Next
Smart cities and connected vehicles promise safer roads, smoother traffic, lower emissions, and better use of urban infrastructure. But all of that depends on getting the electronics right designing and manufacturing hardware that is robust, connected, secure, and scalable.
Electronics manufacturing is not just a back-end step in this story; it’s one of the core enablers. As cities and automakers push forward with new mobility and infrastructure programs, partnering with the right EMS provider can be the difference between a good concept on paper and a reliable solution in the field for the next 10–15 years.
