M2M -> Machine 2 Machine
What is this ?
In a connected world people are online on their computer, mobile or tablet and they want information that is up to date.
So what happens if we connect their car, dog, summer house to Internet, they will now be able to get information about temperature, speed, position and much more.
The next step is that we make it possible for the user to lock or unlock their car, turn on or off the heat in their ski lodge 500 kilometers away.
All above are made possible with M2M or internet of things.
The only limits today is Your fantasy !
