The difference between M2M and IoT – and why it’s important to distinguish between them

Many people use the terms M2M and IoT interchangeably, but did you know that there are significant differences between the two technologies that also make it important to distinguish between them?

In this blog post, we’ll give you a basic understanding of the differences, with a particular focus on how the terms are used in industry and business contexts.

The M2M (Machine-to-Machine) technology connects machines, devices and appliances wirelessly via communication channels, including local area networks and SMS, to deliver services with limited human intervention. This connection upgrades the devices to intelligent assets, opening up a range of optimization opportunities

M2M technology is often used for automation and monitoring, where devices send data to either each other or a control center

Examples of M2M use cases:

• Automation in factories where machines control production processes without human intervention.
• Alarm and monitoring systems that automatically send data to control centers, for example when monitoring temperatures in refrigerators with expensive and sensitive contents. 
• ATMs where the ATM sends transaction data to a central server, which then processes and validates the transaction.

IoT (Internet of Things) refers to a wider network of physical devices connected to the internet. These devices, such as sensors and actuators, collect and share data via internet connections, providing a solid foundation for decision-making based on real-time data.

IoT is used in many different contexts, including:

• Smart home technologies for consumers: Devices like smart thermostats, washing machines and door locks.
• Industrial IoT (IIoT): Optimizing production processes, monitoring equipment and improving safety in industrial environments.
• Energy management: Monitoring and optimizing energy consumption in buildings and factories.
• Optimizing supply: Water utilities save water using IoT technology by monitoring and optimizing water consumption in real time. This is made possible by using sensors to detect leaks and inefficient water use, which can then be quickly corrected.
• Optimizing agriculture: IoT devices are used in agriculture to improve food production. By implementing sensors that monitor soil moisture, temperature and nutrient levels, farmers can optimize their crop production. 

Today, IoT is widely used in private households, but it is especially in business and industry that IoT can create great value and help optimize operations, productivity, maintenance and energy management.

Although M2M and IoT share some common features, there are significant differences between them. We’ve outlined the most notable ones below:

Network

M2M does not necessarily require an internet connection and often uses local networks for data transfer, while IoT devices are connected to the internet and use cloud technology for data processing and storage.

Scalability

IoT systems are designed to be more flexible and easy to scale, making it easy to add new devices to the network. M2M often requires manual setup of each connection, which is more time consuming.

Interoperability

IoT offers greater interoperability by allowing connections between different devices and systems, which makes it more versatile for different applications. M2M systems often require specific programming for each device to communicate.

Data insights and human interaction

IoT systems provide greater data integration and enable users to analyze data and make decisions. M2M systems are more limited in their ability to deliver user-friendly data experiences.

1) The number of IoT devices has surpassed the world population: In 2021, there were over 13 billion IoT devices in use and this number is expected to increase to 30.9 billion by 2025.

2) IoT generates large amounts of data: IoT devices are expected to generate over 79.4 zettabytes of data by 2025 (1 zettabyte = 1 billion terabytes).

3) IoT and M2M are key to Industry 4.0: Both technologies are central components of Industry 4.0, also known as the fourth industrial revolution, where IoT and M2M help enable a more flexible, efficient and sustainable production process.

Conclusion

IoT and M2M are both crucial technologies in business and industry, but they serve different purposes. While M2M focuses on direct machine-to-machine communication without the internet, IoT extends this concept by connecting devices to the internet and creating a more comprehensive network of data and control. By using IoT SIM cards and M2M SIM cards, businesses can ensure reliable and efficient communication between their devices, enabling advanced applications and optimized operations.
