Bmw, Hyundai and others, team up to develop next generation in-vehicle networking

Article by Christian Andrei, on November 24, 2011

Broadcom Corporation, NXP Semiconductors N.V., Freescale Semiconductor, and Harman International recently made the announcement that a special interest group (SIG) will be created to achieve the drive wide scale adoption of Ethernet-based automotive connectivity. The OPEN Alliance (One-Pair Ether-Net) SIG is a joint venture of founding automotive members BMW and Hyundai Motor Company.

It serves to address industry requirements to enhance in-vehicle safety, comfort, and infotainment, while considerably lessening network complexity and cabling costs. More details are available on

The OPEN Alliance is meant to promote the wide scale adoption of 100Mbps Ethernet connectivity and for it to be regarded as the standard in automotive networking applications. In the coming months, it is planning to expand its members to also include more automotive suppliers and manufacturers. It’s believed that the success of the recently established SIG hinges on the increased use of the Broadcom's BroadR-Reach technology as an open standard.

BroadR-Reach technology, which is targeted particularly to meet the strict requirements of the automotive industry, offers a high-performance bandwidth of 100Mbps over an unshielded single twisted pair cable. When the need for costly and burdensome shielded cabling is eliminated, automotive manufacturers are able to reduce connectivity costs and cabling weight.

The initial focus of the founding members is on setting interoperability requirements, third party testing, certification procedures, and higher data rate specification requirements. all interested OPEN Alliance members can apply for license to specification for BroadR-Reach under RAND terms through a license from Broadcom.
