Machine-to-machine, often referred to as M2M, is part of the Internet of Things applications and refers to the exchange of data and information between the industrials machines connected to the internet. These interactions happen through any communication channel, including wired and wireless. The connected objects create an intelligent network of ‘things’ or systems by capturing data about the world around them and sharing it with other connected devices. This means that some processes that are time-consuming or dull can be automated, leaving people able to concentrate on other tasks.
Machine to machine wireless networks can serve to improve the production and efficiency of machines, to enhance the reliability and safety of complex systems, and to promote the life-cycle management for key assets and products.
Is there a difference between IoT & M2M?
Both M2M and IoT both provide remote access to devices, machines and other connected objects. But there are differences between the two. M2M typically focuses on keeping machines running, notifying manufacturers if there’s a fault or if the hardware needs maintenance. IoT on the other hand, is the software used to connect systems and machines together.
Also, M2M devices do not necessarily rely on an internet connection, whereas this is a requirement for IoT devices.
Applications of M2M
The most common applications of M2M can be seen in manufacturing, smart agriculture , sea traffic management and warehousing. Utility companies also use M2M technology in harvesting energy products and in billing customers. Another application is in traffic control, where sensors are used for monitoring speed and volume of traffic. This information is sent across computers that control traffic signals and lights and other devices associated with traffic control. M2M is also used in tracking and regulating inventory in business.
