Industrial Internet Gateways are devices that connect industrial equipment, sensors, and control systems to digital networks. They act as communication bridges, enabling machines to transfer data reliably between operational environments and cloud platforms, remote monitoring systems, or analytics tools. This concept emerged as industries began adopting digital technologies for better visibility, automation, and real-time decision-making.
Before gateways were introduced, industrial machines typically operated in isolation, using different communication protocols that could not interact easily. Today, Industrial Internet Gateways play a central role in modernizing these environments by enabling data exchange, protocol conversion, and secure connectivity.
