This guide will get you up to speed on the current state of IIoT, real-world applications, benefits for enterprises and everything in between. Let’s get started!
What is Industrial IoT or IIoT
Simply put, IIoT introduces internet-like connectivity to machines on factory shop floors, vehicles in transportation yards and technology in other industrial sites to unlock data-driven efficiencies. The core principle that enables Industrial IoT connectivity is – what can be measured and monitored can be optimized. IIoT integrates sensors and connectivity and applies them directly to industrial assets such as machinery, fleet vehicles and employee tools.
Imagine a world where machines can communicate seamlessly and the mass volumes of machine data can turn into informed business insights regarding production quality, equipment health, supply chain visibility and more. In essence, Industrial IoT removes blindspots and makes the physical world’s data accessible for smarter industrial automation.
How does Industrial IoT work
An IIoT ecosystem relies on sensors, connectivity, data processing and analytics working in tandem across three levels:
Edge Layer: Consists of mechanical equipment outfitted with Industrial IoT sensors plus hardware like IoT gateways which aggregate and process data flows from industrial assets before transmission via corporate networks or public clouds.
Platform Layer: Centralized computing infrastructure for receiving, storing and analyzing vast data volumes from industrial sites. On-premise servers or cloud-hosted IoT platforms offer capabilities for managing connected devices plus tools to build custom applications. Enable secure data integration with legacy enterprise systems like ERPs as well.
Application Layer: Refers to the use case-specific IIoT software which presents captured IoT data via dashboards and visualizations. Line operators and facility managers leverage these applications to track overall equipment effectiveness, supply chain movements or other business priorities.
Within an overarching Industrial IoT architecture, you will find common supporting communication systems like LPWAN (low-powered wide area networks – think NB-IoT or LoRaWAN) or WiFi which offer expanded wireless coverage across large physical footprints containing heavy machinery.
Key technologies in IIoT architecture
As IIoT deployments become more varied and complex, the enabling technology mix continues to evolve as well. Here are some core pieces you will find in a modern IIoT technology stack:
- Sensors: Sensors connected to industrial assets like motors, compressors and production lines feed IoT connectivity modules with real-time data. These include temperature, pressure, humidity, vibration, voltage etc. which capture different equipment telemetry readings frequently and reliably.
- Connectivity Protocols: IT infrastructure for seamless communication between sensors, gateways and platform/application layers via standards like Wi-Fi, 5G, Bluetooth LE (Low Energy) etc. LPWAN technologies cover the long range and low power requirements of some implementations.
- Cloud and Compute Infrastructure: Leveraging IaaS from Azure, AWS or hybrid models to quickly scalehosted storage, processing and analytical capacities.
- Analytics and Artificial Intelligence: Insights extraction via statistical modeling, machine learning and AI to guide predictive failure analysis, dynamic scheduling, targeted campaign management etc.
Together, these core information technologies form the nuts and bolts for complete IoT enablement across smart factories, connected products and automated supply chains.
What can IIoT do? Top use cases and applications
Across manufacturing, transportation, utilities and other industrial sectors, Industrial IoT applications are improving safety, increasing efficiency and even creating new revenue streams. Here are some of the most valuable use cases:

Industry 4.0 vs IIoT vs IoT – what’s the Difference?
Considering the exploding popularity of connected solutions, you will often come across several technology terms used rather interchangeably. But some definite distinctions exist between IoT, IIoT and Industry 4.0 which are useful to highlight:
IoT refers broadly to a lot of consumer focused efforts like wearables, smart home appliances, connected vehicles etc leveraging embedded sensors plus internet connectivity.
IIoT deals with adapting similar information technologies specifically to unlock efficiencies plus optimize process reliability surrounding heavy industrial assets mentioned earlier – think drilling equipment on oil fields or factory shop floor machinery.
Industry 4.0 represents the ongoing digital transformation for the manufacturing sector – but fueled by underlying IIoT building blocks like equipment sensors and analytics around production line data.
So in summary:
IoT is the mega-trend umbrella
IIoT focuses IoT components into industrial use cases like predictive maintenance
Industry 4.0 centers on the manufacturing sub-sector evolution via IIoT-enabled smart factories and connected processes
