An overview of Automotive Ethernet 

1000BASE-T1: The latest Ethernet version

From infotainment systems, automated driving, and big data supported IoT devices, electrical automotives have the potential to revolutionize the way we move. The latest version of the Ethernet, 1000BASE-T1 (802.3bp), requires only one pair of UTP cables to reach a data rate of 100Mpbs/1000mpbs. 

Combined with low latency and high bandwidth capacity, car Ethernet makes it possible for automated vehicle functions to operate safely and reliably. However, car Ethernet technologies are still new and require extensive testing to fulfill market legislation requirements across various countries and regions worldwide.

A one-stop-shop for all car Ethernet testing services

Vendors can test and certify a wide range of automotive components at any GRL test facility. Through our collaborations with industry officials, our lab technicians have the expertise to guide you towards fulfilling certification requirements for Ethernet, USB, USB4™, USB Type-C®, Apple MFi, Thunderbolt, Qi Wireless Charging, HDMI®, DisplayPort, e-DisplayPort™, and IoT — Open Alliance and OCF.

Customizable automotive testing services

To ensure that cars can operate smoothly under all environmental circumstances, GRL labs conduct electrical, mechanical, and environmental tests under a wide range of complex conditions. By accounting for factors such as temperature, humidity, pressure, and signal interferences, vendors can test automotives against the elements before moving them out to market.
