"In this Ericsson Mobility Report, we continue to describe the evolution towards the Networked Society. Between 2015 and 2021, the Internet of Things (IoT) is expected to increase at a compounded annual growth rate (CAGR) of 23 percent, making up close to 16 billion of the total forecast 28 billion connected devices in 2021." (p.3) "The number of mobile subscriptions exceeds the population in many countries. This is largely due to inactive subscriptions, multiple device ownership or optimization of subscriptions for different types of calls. This means the number of subscribers is lower than the number of subscriptions. Today there are around 5 billion subscribers compared to 7.4 billion subscriptions." (p.5)
