What is the IIoT? Everything you need to know about the Industrial Internet of Things

The Industrial Internet of Things, or IIoT, refers to the billions of industrial devices — anything from the machines in a factory to the engines inside an aeroplane — that are filled with sensors, connected to wireless networks, and gathering and sharing data. The advent of tiny low cost sensors and high-bandwidth wireless networks now means even the smallest devices can be connected up, given a level of digital intelligence that allows them to be monitored and tracked, and can share data on their status and communicate with other devices. All of this data can then be collected and analysed to make business processes more efficient.
