Difference between loT and M2M

M2M (Machine-to-Machine)

M2M technology was first adopted in manufacturing and industrial settings, in place of other technologies, such as SCADA (supervisory control and data acquisition- software applications for controlling industrial processes, which is the gathering of data in real-time from remote locations in order to control equipment and conditions.)  and remote monitoring( helped remotely manage and control data from equipment).

Applications sectors of M2M are healthcare, business, and insurance.

M2M is also the foundation for the internet of things (IoT).

 

Key features of M2M

·         Low power consumption.

·         Improve the system's ability and effective services.

·         Monitoring abilities that provide the functionality to detect events.

·         Time tolerance, meaning data transfers can be delayed.

·         Time control, meaning data can only be sent or received at specific predetermined periods.

·         Location specific triggers that alert or wake up devices when they enter particular areas.

·         The ability to continually send and receive small amounts of data.

·         Networking of machines (or devices) for the purpose of remote monitoring and control and data exchange.

·         Embedded hardware modules for sensing, actuation, and communication.

·         Various communication protocols can be used for M2M local area networks such as Bluetooth, Modbus, M-Bus, Wireless M-Bus, Power Line Communication (PLC), 6LOWPAN, IEEE 802.15.4, etc. 

Difference between loT and M2M

Sno	Characteristic	M2M	IOT
1	1. Definition	Contain a linear communication channel between various machines.	Multiple devices communicate with each other through sensors and digital connectivity.
		The main purpose is to monitor and control.	Multiple applications, multilabel communication
		Mostly hardware-based Technology	Based on both hardware and software technology
2.	Interactions	Communicate and interaction between machines & devices. Devices exchanging information through cloud infrastructure.	Broader scope than M2M, communicate in a broader range of interactions, between devices /things, things and people, things with applications and people with applications.
3.	Interactivity	Machine-to-machine solutions operate by triggering responses based on an action. It’s mainly a one-way communication.	Communication flows freely. There can be countless scenarios and combinations.
		Vertical applications	Horizontal applications
4.	Connectivity Scope	Wired, wireless, wifi, cellular , etc	Use more sophisticated sensors. Based systems have more flexible and varied connectivity options.
5.	Solutions	Limited scope. Creating a network of machines that work in synchronization.	Allow for flexible responses and multi-level communication.
6.	Communications	Point to point communication is usually embedded within hardware at the customer site	Devices communicate using IP networks, incorporating varying communication protocols. Supports cloud communication
		Devices do not necessarily rely on an Internet connection	Devices relay on an internet connection
		Use non IP protocol	Uses IP protocol
		Structure data	Structured and unstructured data
7.	Integration	Limited integration option.,	Unlimited integration options but required software that manage Communications/  protocols
		Deployed in a closed system	Open system, connected to a large network
