A device with sensors, a network for transmitting data, and a system that can process this to trigger actions. These are the components of the Internet of Things. It sounds complex, but we are in fact already using it to simplify lots of things. For example, car parks transmit their occupancy, recycling containers show their fill level or heating systems highlight possible failures.
There is huge potential in the Internet of Things. According to market researchers, by 2023, several billion ‘things’ will have been networked worldwide. Some sources claim that, even today, the number of networked things has already surpassed the number of smartphones in use worldwide. Network equipment supplier Ericsson is forecasting an annual growth in IoT devices at a rate of 20 percent for local IoT devices, and 30 percent for wide area IoT. By contrast, mobile phones have only grown by three percent.
