Automotive Ethernet: The core infrastructure for next-generation vehicle networks

Automotive Ethernet has become the communication backbone of modern vehicles, enabling high-speed, deterministic and scalable data exchange across ECUs, sensors and domain controllers. Based on IEEE 802.3 standards such as 100BASE-T1 and 1000BASE-T1, it supports advanced applications in ADAS, infotainment and electric mobility.

This section brings together STAR ELECTRONICS’ technical insights, guides and validation resources on key Automotive Ethernet technologies — including TSN, TC10, MACsec, PoE, and energy-efficient networking — to help engineers design reliable and compliant in-vehicle communication systems.
