What Is an IoT Gateway and Why Is It Crucial for IoT Systems?

[johnharry24]

An IoT gateway is a hardware or software bridge that connects IoT devices to the cloud or data center. It gathers data from sensors and devices, filters and processes it locally, and then transmits it securely to remote servers. This reduces bandwidth use and ensures faster response times. The gateway also adds a layer of security by protecting internal devices from external threats. In industrial IoT, smart cities, or agriculture, an IoT gateway helps maintain reliable and efficient communication between field devices and control systems. It's the backbone of any robust IoT architecture.
