The internet of things will have nearly one-third more devices by the end of this year, though many of them won’t exactly be exotic.
There will be 8.4 billion IoT devices in use at the end of 2017, up 31 percent from the end of 2016, Gartner estimated on Tuesday. That’s slightly faster than the growth rate last year. The number will keep growing at about the same pace until 2020, when there will be just over 20 billion devices, the research company says.
