About Realtek

Founded in Hsinchu Science Park in 1987, Realtek is a fabless semiconductor company focused on communications-network, connected-media, computer-peripheral and multimedia ICs. Its portfolio spans Ethernet controllers, wireless LAN and Bluetooth chips, router SoCs, audio codecs, camera controllers and other mixed-signal connectivity products.

The robotics connection is traceable across a live multi-tier bill of materials. ALFA Network specifies the RTL8821CU inside its AWUS036EACS adapter, while ModalAI names that adapter as the data-transmission device in Starling 2 Max. Korthos therefore records Realtek at the control-and-connectivity chip layer; it does not infer that every Realtek wireless product is robotics-specific.

Timeline

Events

  • 2026-08-17 - Capability - Realtek showcases integrated communication solutions for humanoid and industrial robots at WRC 2026

    Realtek presented EtherCAT MCU drivers, single-pair Ethernet PHYs, Ethernet switches, high-speed image transmission, USB/Type-C interfaces, and wireless modules for humanoid and industrial robots. The EtherCAT solution targets servo control and multi-axis synchronization, while 100/1000BASE-T1 PHYs target lightweight, real-time links between drives, sensors, and control units. Realtek also showed 8GE+2×10GE switching, ASA-ML SerDes for low-latency vision data, and Wi-Fi 7/6E/8 plus Thread, Zigbee, and Bluetooth for remote control and multi-robot data exchange.
