Internet-connected devices to reach 100B by 2020

There will be 100 billion devices connected to the Internet by 2020 as compared to just 9 billion in 2014, according to market research firm Radiant Insights.

That's twice as many as the estimate from Cisco Systems Inc., which has been widely used by proponents of the Internet of Things (IoT). Radiant's figure represents a compound annual growth rate (CAGR) over the period of about 50 per cent. It is also four times higher than the 26 billion figure estimated by Gartner.

But as a result of this explosion of connectivity the worldwide market for chips supplying wireless sensor networks is set to grow from $2.7 billion in 2013 and reach $12 billion by 2020. This is a CAGR over the period of 23 per cent.

Radiant predicts that wireless sensor networks will be used to monitor and control many domestic, urban and industrial systems. As such this promises to produce an explosion of data much of which will be discarded as users are overwhelmed by the volume. As a result, analysis of the data within the wireless sensor network will become necessary so that alerts and meaningful information are generated at the leaf nodes.

The change from wired networks to wireless networks will add to the growth as wireless networks can have a broader reach than wired networks and are more flexible and extensible.
