Ethernet Gateways are networking devices that connect IoT nodes or industrial devices to local area networks (LANs) or enterprise systems using wired Ethernet connections. They act as a bridge between field-level devices and centralized servers, controllers, or cloud platforms, enabling reliable, high-speed, and low-latency data transmission.

Ethernet gateways are widely used in industrial automation, building management, smart infrastructure, and manufacturing environments, where stable and continuous connectivity is critical. They support multiple protocols, including Modbus, OPC UA, MQTT, and other industrial or IoT communication standards.

These gateways often include data aggregation, edge processing, and security features, ensuring seamless and secure integration of field devices into enterprise networks. By providing real-time monitoring, control, and data flow, Ethernet gateways enable organizations to optimize operations, improve system performance, and support intelligent automation initiatives.

Modern Ethernet gateways are robust, scalable, and designed for continuous operation, making them a key component in IoT and industrial networking architectures, bridging physical assets with digital systems to enable data-driven decision-making, operational efficiency, and smart infrastructure management.
