6 years ago, Ericsson hyped IoT by forecasting 50 billion internet connected devices by 2020. Some others had stretched it with projections of up to 1.5 trillion.
But just before Christmas, in their latest Mobility Report, Ericsson quietly changed their minds. They still kept the headline number of around 50 billion connected devices, but dropped the number of cellular connected IoT devices in 2020 from their previous estimate of 20 billion to just over 1 billion. The important word here is cellular.

What seems to be the problem?
An Ericsson report released earlier this year shows that the reason for this could be the fact that the majority of IoT components would be connecting through a capillary network.
However, Nick goes on to say that a capillary network is just a fancy name for a local network where devices would connect through WiFi,
Bluetooth, igbee or even cables to reach out to the web.
The IoT market in 2020 might not look much different from today’s M2M market, dominated by higher value applications in vertical markets. You can read the full PDF published by Nick Hunn at the source link below.
