Machine-to-Machine (M2M) refers to the direct communication between devices without human intervention. This technology enables machines to exchange data and perform tasks automatically, improving efficiency in various industries. M2M is commonly used in applications like smart meters, industrial automation, and healthcare monitoring. M2M communication typically relies on wireless networks, such as cellular, Wi-Fi, or Bluetooth, to connect devices. By sharing information in real-time, M2M systems can optimize operations, reduce costs, and enhance decision-making. This technology plays a crucial role in the development of the Internet of Things (IoT), where interconnected devices work together to create smarter environments.
