An
IoT gateway is a key component in any IoT ecosystem. It acts as a bridge between IoT devices and the cloud, collecting, filtering, and transmitting data. Without an IoT gateway, many IoT devices would struggle to communicate efficiently due to differences in network protocols. By providing security, local processing, and data filtering, IoT gateways help reduce network load. They also ensure that sensitive or unnecessary data doesn’t leave the local environment. Whether for smart water systems or industrial IoT applications, IoT gateways are critical for secure, stable, and efficient operations.
