An IoT gateway is a crucial bridge that connects IoT devices to the cloud or central data systems. It collects data from sensors and devices, processes it locally, and then transmits it to the internet for analysis. Without an IoT gateway, most IoT deployments cannot function efficiently due to connectivity issues or data overload. It enables secure communication, filters data, and even supports real-time decision-making. In short, the IoT gateway is the backbone of a scalable, reliable IoT system.
