M2M Communication, or Machine-to-Machine 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. Common applications include smart meters, industrial automation, and connected vehicles. M2M Communication relies on various communication protocols and technologies, such as Internet of Things (IoT) and cellular networks. By facilitating real-time data transfer, M2M enhances efficiency and decision-making in various sectors, including healthcare, agriculture, and transportation. This interconnectedness is crucial for developing smart cities and improving overall operational performance.
