Ethernet on wheels

CESA 2012 Partner 

Ethernet on wheels … is not really groundbreaking news, some may say. No argument here, since 100Mbps Ethernet has been around for a while as an on-board diagnostics (OBD) port and access point to the vehicle for re-programming or flashing modules at the OEM dealership. The news is that the automotive industry is making strong efforts to standardize Ethernet as in-vehicle network for high bandwidth applications such as cameras and multimedia. Up to now, high bandwidth meant proprietary network architectures with cumbersome cabling, expensive physical interface devices, custom tools and limited supplier base.

Recently, Broadcom, BMW, NXP, Freescale, Hyundai Motor Company and Harman announced the formation of the OPEN Alliance SIG* (One-Pair Ether-Net Special Interest Group). The alliance’s goal is to enable wide scale adoption of Ethernet in automotive, establish industry standards for Ethernet connectivity over a single pair unshielded cable and enable migration from closed application to open, scalable Ethernet-based network.
