Here is a good illustration of the vast reality of the Internet of Things – and at the same time an illustration of what it means.
The top right section clearly shows the Internet of Things: smart objects with an IP address which can sense (depending on use case, gather data on various parameters such as location, temperature, moisture level and dozens of more possibilities). This data gets sent for processing or analyzed at the source.
The upper left section is the ‘Internet of People’. Think about everything you use to connect with the Internet, such as your smartphone. It’s in the meeting of this sphere and the Internet of Things that most Internet of Things consumer applications today get born. Several so-called Consumer IoT (CIoT) applications such as wearables can’t live without smartphones. Moreover, for several control and monitoring activities you’ll need some sort of device such as a tablet, for example in a smart home context.
The sphere at the bottom of the image is composed of all connected objects that do not have an IP address and do not belong to the Internet of Things. They exist since a long time, mainly in the sphere of industrial Internet and we see them migrate to the Industrial Internet of Things (IIoT). Replacing such devices or tagging them so they become IoT-enabled is a part of what happens in IIoT.
