What is Machine-to-Machine or M2M?

Machine-to-Machine, or M2M, refers to direct communication between devices using wireless, wired, or any other communication channel. M2M operations are common among smart devices.

A smart device autonomously performs tasks, communicates with other devices, adapts, and learns from data without human intervention. Examples include smart fridges, smart TVs, smart locks, smart home assistants, and autonomous vehicles.

Techopedia.com has the following definition of the term:

“Machine-to-Machine (M2M) refers to a wireless or wired network setup that allows devices of the same type and ability to communicate freely.”

“This type of system can be used in a variety of ways and has advanced over the last few decades with the creation of global Internet and IP network systems, facilitating enhanced and efficient communications over long distances and between large numbers of devices.”

Machine-to-machine and IoT

The concept of M2M is a cornerstone of IoT (the Internet of Things), where devices are able to connect and exchange information with no human intervention.

Your morning alarm clock, for example, not only wakes you up but also notifies your coffee market to start brewing. That is M2M in action.

Put simply, M2M involves two or more machines “talking” or sending data to each other, autonomously, that is, without human involvement.

Far-reaching implications

This technology is not just about convenience in our daily lives, it has far-reaching implications. In healthcare, M2M technology can monitor patients remotely. Small devices can send vital patient data to medical professionals who may be located in another town or even a different country.

M2M can significantly streamline business processes. Vending machines and smart shelves in warehouses and retail stores can automatically request a refill or restock when necessary. This means that there is less waste, more efficient supply chains, and better inventory management.
