The purpose of machine-to-machine (M2M) communication is to enable direct data transmission between devices without human intervention. This technology facilitates the exchange of information across a network, allowing devices to communicate, analyze data, and perform tasks autonomously. M2M is critical in various applications, such as smart homes, IoT (Internet of Things), and industrial automation, where systems can monitor and control processes efficiently. By automating communication, M2M enhances operational efficiency, reduces human error, and supports real-time decision-making in various sectors.
