Internet of Things (IoT) gateways are crucial components in the IoT ecosystem. They act as a bridge between devices and the cloud, enabling smooth communication and data flow. IoT gateways collect data from connected devices, perform necessary processing and analysis, and send it to the cloud. They also ensure security by implementing protocols to protect the data during transmission. IoT gateways are particularly vital in industrial settings, where they can integrate with systems like industrial wireless routers and LANs to facilitate robust, secure, and efficient IoT implementations.
