What is M2M?
A part of modern ICT landscapes
M2M stands for Machine-to-Machine Communication and
describes the automatic exchange of information between machines
and devices. M2M is closely related to concepts such as
the Internet of Things (IoT), Cyber Physical
Systems (CPS), Industry 4.0, and Smart Cities.
They all map out scenarios in which the things around us - from
machines in manufacturing to everyday objects - exchange and
evaluate data automatically and create added value for private life
and work. Since large amounts of data need to be stored and
interpreted in the process, Machine-to-Machine communication goes
hand in hand with developments like Cloud
Computing and Big Data Analytics.
Computerized and connected physical objects
M2M solutions typically share the following design principles:
Sensors and IT components that are integrated in or attached to
objects gather data like operating conditions, GPS coordinates,
power consumption and light intensity (1). Captured data is relayed
to a server via mobile or fixed-line networks (2). There, the data
is stored and evaluated (3). If the sensor and machine data meets
certain reassigned criteria, further actions are set in motion -
alerting the solution's operator via SMS for example (4).
A promising prospect for our business and private lives
Machine-to-machine communication ranks among the core technologies
that are about to solve pressing problems of our information
society. When machines and things talk to each other and handle
both business-related and mundane tasks automatically, they
increase our economic efficiency, ensure the quality of life of
aging populations, and lead to environmental sustainability.
