The Different "Speeds" of Automotive Ethernet: 100BASE-T1 to 10GBASE-T1
"Automotive Ethernet" is an umbrella term for several standards. 100BASE-T1 is the common foundation, providing 100 Mbps for core infotainment and basic ADAS. 1000BASE-T1 (1 Gbps) handles high-resolution displays and advanced sensor fusion. The cutting edge is 10GBASE-T1 (10 Gbps), designed for raw data from autonomous driving sensors (LiDAR, radar arrays) and centralized high-performance computers. A single car will often use a mix of these speeds.
FAQ:
Q: Why not just use the fastest standard everywhere?
A: Cost and complexity. Using 10 Gbps links for simple tasks like window control is overkill and would increase cost and power consumption unnecessarily. The right speed is matched to the task.
Q: Who are the main suppliers of Automotive Ethernet technology?
