Automotive Ethernet Device and Network Testing

10BASE-T1S technology was developed as part of the IEEE 802.3cg-2019 standard to enhance in-vehicle Ethernet networks by providing Ethernet-to-the-edge connectivity, which is essential for zonal-based automotive architectures. It offers a cost-effective solution by utilizing a multidrop bus topology, allowing multiple devices to connect via a single unshielded twisted pair cable without the need for switches or gateways. This brief provides an overview of 10BASE-T1S technology, including related benefits, testing challenges and key testing considerations, along with setup and configuration guidelines to ensure optimal performance and reliability in both peer-to-peer and multidrop environments.

Read how 10BASE-T1S Ethernet delivers new benefits making it highly suitable for a broad range of automotive applications, including sensors and actuators across multiple domains.

Watch the demo to see how Spirent TTsuite-OPEN-EthernetSwitch enables users to validate the compliance of an Ethernet switch as part of an in-vehicle network.

The next-generation Ethernet standard "IEEE 802.1 TSN (Time-Sensitive Networking)" is a protocol for achieving real-time performance. Since the transmitted data can be delivered within the set time according to the priority, it is expected to be used in industrial equipment and in-vehicle networks that require precise control.
