According to the recently released Annual Internet Forecast by Cisco there will be close to 30 billion devices connected to the internet, versus some 5 billion people, that makes 6 times more devices than people. Some of these devices, like tablets, phones… will be gateways for people, so one may argue that they should not really count as “machines”, but 50% of the devices will be IoT of different sorts and these are indeed machines. Hence the estimate that there will be 3 times more machines than humans connected to the Internet. Or, if you want, internet will be serving machines rather than people …
As it could be expected the growth is expected in all types of devices but the highest increase is expected on IoT and in general machine communications. The second growth is foreseen by smartphone (27% CAGR but this is now levelling out as their are starting to saturate the market) whilst tablet and PCs are expected to grow at a single digit (4 and 7% respectively).
Smart televisions, on the other hand, are expected to replace existing televisions over this time frame leading to a CAGR of 13%.
Also interesting the forecast that close to 50% of connected devices will be using wireless connectivity.
