However, for a book such as this, we believe that it is helpful to have a clearly defined scope and give it an explicit name. In this section, we will explain the origins of Enterprise IoT and provide a definition.
From M2M Toward the IoT
The idea of connecting devices and applications is not new. Specialized telematics solutions have been around for a long time. Over the last decade, machine-to-machine (M2M) communication became widely established, a development driven by players such as telecommunications companies looking for new ways to leverage their existing mobile networks. So what is the difference between M2M and IoT? There is no black-and-white answer to this question, but Figure 2-1offers some general observations.
Figure 2-1. From M2M to IoT
The following excerpt from [MR13] summarizes what we feel to be the most important points:
