Broadcom and Hyundai have signed a joint development agreement to use ethernet-based networking for in-car infotainment.

The collaboration aims to integrate infotainment, telematics and advanced driver assistance systems into Hyundai vehicles using Broadcom's BroadR-Reach ethernet technology.

Last November, carmakers BMW and Hyundai teamed up with Broadcom, NXP Semiconductors, Freescale and Harman to make ethernet the computer networking technology of choice inside the car. The alliance, which is called OPEN (one-pair ethernet) wants to establish BroadR-Reach as an open standard for in-car connectivity.

Broadcom, a US based supplier of semiconductors and connectivity solutions, said the use of ethernet will help lower in-car connectivity costs.

"Our collaboration with Hyundai Motor will make features previously only available in luxury models accessible to a broader number of drivers, ultimately improving automotive safety for the masses," Ali Abaye, senior director, product marketing at Broadcom, said in a press release.

Hyundai said it is confident ethernet provides a viable connectivity solution for the car. Said Hyundai Infotainment Design Division Leader SunJai Lee: "The in-vehicle Ethernet network will enable key features including infotainment, lane departure warning, park assist and telematics to deliver greater value to our customers."

Automakers need in-car connectivity that can handle more data-heavy applications in a cost-effective way. Broadcom’s BroadR-Reach technology can operate over single unshielded twisted pair (UTP) cabling, wich is less expensive and weighs less than shielded cable.
