Hyundai to wire cars with Broadcom ethernet tech, put infotainment and security systems on one network

Cars wired with ethernet may conjure thoughts of roving internet hotspots, but that's not what Hyundai and Broadcom have in mind in this case. Traditionally, infotainment consoles, safety systems and the like are built on multiple in-car networks, but the duo will rig vehicles with modified ethernet cables to unify some of the disparate systems on a single network. Dubbed BroadR-Reach, the tech uses a single pair of unshielded wires to offer 100Mbps connection speeds and could scale up to 1Gbps. Though Hyundai and other automakers joined with Broadcom's standards group for the technology last year, the firm is now the second car manufacturer to pledge that its autos will get the tech. As of now, there's still no word on which models will be lined with ethernet or when they'll roll off assembly lines.

Broadcom and Hyundai Motor Power Next-Generation Connected Car

Joint Development Enables Advanced Infotainment and Safety Features in Hyundai Vehicles

DETROIT, Oct. 15, 2012 News Highlights:

  • Advances wide-scale adoption of automotive Ethernet

  • Extends infotainment and passenger safety features across price points

  • Delivers 100Mbps connectivity for in-vehicle networks, with future scalability up to 1Gbps

Broadcom Corporation (NASDAQ: BRCM), a global innovation leader in semiconductor solutions for wired and wireless communications, today announced a joint development agreement with Hyundai Motor to power the next-generation connected car. The collaboration will integrate infotainment, telematics and Advanced Driver Assistance Systems (ADAS) features such as surround view parking and lane departure warning into Hyundai vehicles. Together, the companies aim to deliver robust features and faster connectivity to a broader number of drivers. Visit to learn more.

Based on Broadcom's BroadR-Reach® Ethernet technology, the single high-bandwidth in-vehicle network will deliver cost-effective, lightweight 100Mbps connectivity to advance integration of safety applications in the vehicle. Broadcom will showcase the technology at SAE Convergence in Detroit, October 16-17.

As members of the AVnu Alliance and OPEN Alliance (One-Pair Ether-Net) Special Interest Group (SIG), Broadcom and Hyundai Motor have partnered since 2011 to drive wide-scale adoption of Ethernet-based automotive connectivity. Ethernet enables an open, scalable network for powering in-vehicle infotainment and ADAS, while supporting faster implementation of next-generation technologies and multiple networks, improving the ability to share data from a common source to the entire network.

BroadR-Reach Ethernet also supports the IEEE 802.1 Audio Video Bridging (AVB) standard, a key technology for achieving high quality audio and video transmission in automotive by providing guaranteed quality of service (QoS), frame synchronization and timing necessary to stream professional-quality audio and video traffic.
