Macro Perspective examines total market and various verticals or segments in it. Technology adoption rate and barriers & Challenges and also specific application requirements in various segments are the focus of this perspective
Various IoT technologies can be categorized into tagging things, sensing things
and embedded things.
The tagging things provide item identification, allowing the things to be connected with their records in databases.
The sensing things enable us to measure and detect changes in the physical status of our environment.
Finally, the embedded things yield information about the internal status of the embedding object.
The estimates of the market size vary.
The number of connected devices is expected to grow from 9 billion in 2011 to 24
billion in 2020. The most drastic growth is assumed to take place in Machine to Machine
connections, from 2 billion at the end of 2011 to 12 billion by the end of 2020 according to GSMA 2011..
But, according to Gartner, already in 2011, the population of connected things comprised over 15 billion permanent and over 50 billion intermittent connections, and these numbers are forecasted to
increase to over 30 billion and over 200 billion, respectively, by 2020 (Cearley 2011).
The total revenue generated by connected devices for data transfer or tele communicaton compnaies will from EUR420 billion in 2010 to EUR1.3 trillion by 2020. (GSMA 2011).
