Product Specifications

Technical details and manufacturing context for Network Interface Controller(s)

Definition
A Network Interface Controller (NIC) is an essential hardware component within an IoT Gateway that provides the physical interface and manages data transmission between the gateway and various networks (e.g., Ethernet, Wi-Fi, cellular). It handles protocol conversion, data packet processing, and network communication, enabling the gateway to connect sensors, devices, and cloud platforms.
Working Principle
The NIC receives digital data from the IoT Gateway's main processor, converts it into electrical signals (or radio waves for wireless NICs) according to network protocols (e.g., TCP/IP), and transmits it over the physical network medium. Conversely, it receives incoming signals, converts them back to digital data, and passes them to the gateway for processing. It manages tasks like MAC addressing, error checking, and data flow control.
