What is M2M? Definition, Key components, Applications & Benefits

M2M communication

M2M – Machine to Machine Communication:

To understand M2M communication, check below example

If your vehicle could talk.


  • I’m on time for delivery.
  • I’m driving too fast.
  • My engine needs a tune-up! etc

What would you say?

This is an example of M2M communication.

Definition of M2M:

M2M (Machine to Machine) is a concept that enables networked devices to perform actions by exchange information without the manual assistance of humans.

Machine to Machine refers to direct communication between devices using wired or wireless communications channel.

It is quite similar to the Internet of Things concept but both carry some difference.

Key Components for M2M System:

Key components of an M2M system include

  • Sensors,
  • RFID,
  • a Wi-Fi or cellular communications link and
  • To help a networked device to interpret data and make decisions, the need for Autonomic Computing software programmed.

Machine to machine communication can include industrial instrumentation,

  • Enabling a sensor to communicate the data it records (such as temperature, inventory level, etc.) to application software
  • This application software can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory).

Applications of Machine to Machine communication:

M2M communication is often used for

  • Remote monitoring
  • Product restocking (a vending machine can generate an alert or message the distributor when a particular item is running low)
  • In Warehouse management to remote control, robotics, traffic control, supply chain management, fleet management, logistic services, and telemedicine services.

Products built with Machine to Machine communication capabilities are often marketed to end-users as being “smart.”

Such communication initiated by a remote network of machines generated information sent to a central hub for analysis, which would then share with a system like a personal computer.

Benefits of Machine to Machine: 

M2M wireless networks can use to

  • Improve the efficiency and production of machines,
  • To increase the reliability and safety of complex systems, and
  • To encourage the life-cycle management for key assets and products.

By applying Prognosis and Health Management (PHM) techniques in machine networks, the following can achieve

  • Health management of a fleet of similar machines
  • Near-zero downtime performance of machines and system.
