Ericsson predicts that, in 2018, Internet of Things (connected cars, machines, utility meters, remote metering and consumer electronics) connections will outnumber mobile connections used by people.
Some might argue that forecast is more robust than others expect, since it includes consumer electronics connections that we do not all agree are IoT connections at all. To be sure, many include wearable devices within the IoT category. Others might use a more-restrictive definition.
But Ericsson forecasts that IoT device connections will grow at a compounded annual growth rate (CAGR) of 23 percent from 2015 to 2021.
In total, around 28 billion connected devices are forecast by 2021, of which close to 16 billion will be related to IoT.
There were around 400 million IoT devices connected by mobile subscriptions at the end of 2015.
Mobile IoT connections will reach 1.5 billion in 2021, Ericsson argues.
