Differences between IoT & M2M by Neha Verma & Parag Mittal

13 Differences Between IoT & M2M

Machine-to-Machine (M2M) and Internet of Things (IoT) are systems that enable devices to transfer data and support the automation of data-driven processes and actions. This helps enterprises to improve efficiency with minimal human interaction. What are the key differences between IoT & M2M?

What is Machine-to-Machine (M2M)?

M2M communication is a solution that connects two or more machines, enabling them to interact and relay data without any human involvement. 

What is Machine-to-Machine (M2M)?

How does M2M work?

The M2M system has multiple sensors, an RFID, Wi-Fi, or cellular communications link. Sensors communicate key parameters to the computer. This form of communication takes automated sensor data and transfers it over networks like cellular or Ethernet, which makes it cost- effective.

M2M Use Cases

  1. Telematics -  Telematics is an industry that highly depends on M2M. Telematics applications include a range of services like vehicle tracking, fleet management, satellite navigation and emergency warning systems to name a few. One of the original use cases in the industry is sensor telemetry, that helps in monitoring factors like temperature, energy consumption, pressure, moisture etc.
  2. ATMs - Sensors in the ATM machines send a signal whenever it’s low on cash. This data-transfer ensures efficiency.
  3. Vending Machines - Sensor detects when a particular product is running low in a vending machine. This data is transmitted through Wi-Fi or cellular networks to the fulfillment center.

Some other prominent examples of M2M use cases are

  • Smart meters
  • Asset tracking
  • HVAC systems
  • Smart factories

What is Internet Of Things (IoT)?

IoT is the network of devices that are embedded with sensors, software, and other technologies to connect and transmit data with other devices & systems over the internet. These devices range from household objects to sophisticated industrial machinery that can be automated, controlled and monitored on-site or remotely by users.

What is Internet of Things (IoT)?

How Does IoT Work?

While M2M is the communication between devices to transmit and collect data, Internet of Things (IoT) builds on that technology to offer user applications. Now machines can interact not just amongst themselves, but also with humans through applications powered by cloud and network integrations.

IoT Use Cases

There are many popular examples of IoT devices around us today. Google Home and Alexa have become common household names. However, the first IoT device dates back to the 1980s and was invented by a Carnegie Mellon University student. He upgraded a Coca Cola vending machine to get information of soda availability on a board in his room.

Other than connecting regular household items, IoT has a major role to play in connecting devices in various industries. Enterprise applications of IoT have a larger impact on a company’s efficiency. Use cases of IoT include -

  • Wearables
  • Tracking devices
  • Smart homes
  • Healthcare 

Key Differences between IoT & M2M? 

The major difference between IoT and M2M is that M2M is used to make the connection between multiple devices whereas IoT is used to make connections of devices for information availability and subsequent human actions. The Internet of Things is an extension of Machine-to-Machine.
