M2M (Machine to Machine), also known as Machine Type Communication (MTC) in 3GPP, can be seen as the first generation of connected objects. As opposed to H2H (Human to Human), which in telecoms is associated with mobile and smartphone communications, for example, M2M is characterized by a number of different scenarios relating to health, security, transport, industry, etc., potentially involving a large number of machines or objects, low cost and energy consumption issues, and data exchanges that are sometimes sporadic and of very low volume.
