Machine-to-machine (M2M) communication refers to the direct exchange of data between devices without human intervention. This technology enables devices to communicate over networks, allowing them to share information and perform tasks automatically. M2M is commonly used in various applications, such as smart meters, industrial automation, and connected vehicles. The benefits of M2M communication include increased efficiency, reduced operational costs, and improved data accuracy. By enabling devices to work together, M2M can streamline processes and enhance decision-making. This technology is a key component of the broader Internet of Things (IoT), where interconnected devices collaborate to create smarter environments.
