A History of IIoT:

The concept of the IIoT has its roots in the development of the internet and the proliferation of connected devices in the late 20th century. The term "Industrial Internet of Things" was coined by General Electric (GE) in a 2011 white paper, which described the integration of internet and operational technology (OT) in industrial environments. However, the implementation of IIoT technologies can be traced back to the 1990s, with the introduction of the first programmable logic controllers (PLCs) and the development of fieldbus technologies, which allowed industrial devices to be connected and controlled remotely.

Since then, IIoT has evolved significantly, with the proliferation of sensors, cloud computing, and advanced analytics, which have enabled industries to collect, process, and analyze vast amounts of data from their connected devices. The IIoT has also been driven by the emergence of low-cost and low-power communication technologies, such as Zigbee and Bluetooth, which have enabled the deployment of IoT solutions in industrial environments.

Current state of IIoT:

Today, IIoT is being used across a wide range of industries, including manufacturing, transportation, energy, and healthcare. It is enabling industries to optimize their operations, improve efficiency, and reduce costs by providing real-time insights into their systems and processes. Some of the key benefits of IIoT include:

  • Improved asset utilization and maintenance: By collecting data from sensors and other connected devices, industries can monitor the performance and health of their assets in real-time, and take preventative measures to avoid downtime and extend the lifespan of their equipment.
  • Enhanced productivity and efficiency: IIoT can help industries automate their processes and optimize their supply chain by providing real-time visibility into their operations. This can lead to improved productivity, reduced waste, and lower costs.
  • Increased customer satisfaction: IIoT can help industries provide better products and services to their customers by enabling them to monitor and track their products throughout the supply chain, and respond to customer needs in real-time.

Future developments:

As the IIoT continues to evolve, it is expected to have a significant impact on a wide range of industries. Some of the key areas where IIoT is expected to drive innovation and change include:

  • Artificial intelligence and machine learning: IIoT will enable industries to collect and analyze vast amounts of data from their connected devices, which can be used to train and improve the performance of machine learning algorithms. This will enable industries to automate and optimize their operations, and make better informed decisions.
  • Edge computing: With the increasing volume of data being generated by IIoT devices, there is a growing need for efficient and cost-effective ways to process and analyze this data. Edge computing, which involves processing data at the edge of the network, close to the data source, is expected to play a key role in meeting this demand.
  • 5G and other communication technologies: The emergence of 5G and other high-speed communication technologies will enable industries to deploy IIoT solutions at a larger scale, and support the real-time data exchange and processing required for many IIoT
  • Cybersecurity: As the IIoT connects more devices, machines, and systems to the internet, it is critical to ensure the security and integrity of this data. Industries will need to invest in robust cybersecurity measures to protect against cyber threats and prevent data breaches.
  • Ethical and legal considerations: The IIoT will generate vast amounts of data that can be used to make decisions about individuals and organizations. This raises ethical and legal questions about the use and privacy of this data. Industries will need to ensure that they are transparent about how they collect, use, and protect this data, and that they are compliant with relevant laws and regulations.

Technical aspects of the Industrial Internet of Things (IIoT):
  • Connectivity: IIoT devices typically use a variety of communication technologies to connect to the internet, such as Wi-Fi, cellular, Zigbee, Bluetooth, and others. These technologies enable the devices to exchange data and communicate with other devices, systems, and the cloud.
  • Sensors: IIoT devices often include sensors that can collect data from the environment or from the device itself. This data can be used to monitor and control the device, as well as to provide insights into the system or process in which the device is used.
  • Data processing: IIoT devices often have limited processing power and storage capacity, so they rely on the cloud or other external systems to process and analyze the data they collect. This can be done using advanced analytics techniques, such as machine learning and artificial intelligence, to extract valuable insights and make informed decisions.
  • Edge computing: In some cases, it may not be practical or cost-effective to transmit all the data collected by IIoT devices to the cloud for processing. Edge computing allows some of the data processing and analysis to be done at the edge of the network, closer to the data source, which can reduce latency and improve efficiency.
  • Cybersecurity: IIoT devices are vulnerable to cyber threats, such as malware, hacking, and data breaches, so it is important to ensure that they are secure. This can be done using a variety of cybersecurity measures, such as encryption, firewalls, and authentication protocols.
  • Integration: IIoT systems often involve the integration of a variety of devices, systems, and platforms, so it is important to ensure that they can communicate and exchange data effectively. This can be done using standard protocols, such as MQTT, HTTP, and OPC-UA, or using custom integrations.
  • Scalability: As IIoT systems grow and expand, it is important to ensure that they can scale to meet the increasing demand for data processing and storage. This can be done using cloud computing, edge computing, or a combination of both.


The IIoT is transforming the way industries operate, by providing real-time insights into their systems and processes, and enabling them to optimize and automate their operations. While the IIoT has already had a significant impact, it is expected to continue to drive innovation and change in the future. Industries will need to keep up with these developments and ensure that they have the necessary skills, infrastructure, and cybersecurity measures in place to take full advantage of the IIoT.
