An IoT gateway is a device that connects IoT sensors and devices to the cloud or data center. It collects data from local devices, filters it, and sends it to the internet for processing. This reduces network traffic and improves efficiency. The IoT gateway also adds a layer of security between devices and the internet. It’s essential for real-time data transmission and remote monitoring. Without it, large IoT systems can become unreliable.
