10BASE-T1S/L Connects sensors in cars and buildings

June 27, 2024

In 2019, IEEE published 802.3cg, which added clauses 146 and 147 to its Ethernet 802.3 standard, which created 10BASE-T1S (short reach) and 10BASE-T1L (long reach). These two Ethernet flavors can serve vehicles and industry, respectively, where few wires take priority over high speed. Automotive Single-Pair Ethernet (SPE) 1000BASE-T still has a place in vehicles for infotainment and assisted driving. Many automotive and industrial sensors don’t need high-speed links but need data and power.

The automotive industry has shown interest...

May 31, 2018

The automotive industry is adopting self-driving cars as the next major evolutionary step in vehicular technology. However, improvements need to be made to data buses inside the car to support the additional data needed for a car to operate autonomously. Ethernet and the Mobile Industry Processor Interface (MIPI) are replacing previous network technologies, allowing for the next generation of autonomous vehicles through faster data rates and lower latency.

Introduction

For the better part of the last...
