Connected car automotive Ethernet specs ready

twistedpaireithernetThe OPEN Alliance (One-Pair EtherNet) Special Interest Group (SIG), published its automotive Ethernet specifications. The release of the specifications is to help establish single pair Ethernet as the connectivity technology of choice for connected cars.

Single pair Ethernet offers high bandwidth, price-performance, ubiquity and inherent network security features, making it great for automotive use.

BroadR-Reach Ethernet technology allows multiple in-vehicle systems (such as infotainment, automated driver assistance and on board-diagnostics) to simultaneously access information over a single unshielded twisted pair cable. By eliminating the need for expensive, shielded cabling, automotive manufacturers canĀ  reduce connectivity costs and cabling weight. Ethernet technology delivers high-performance bandwidth of 100 Mbps per port while dramatically reducing connectivity costs and cabling weight.

By making the specifications widely available, the SIG hopes that it can help further drive wide scale adoption

Analysts predict the automotive Ethernet segment to grow exponentially over the coming years, with 15 to 20 automotive Ethernet ports per vehicle by 2020.

Membership in the automotive OPEN Alliance SIG has grown significantly to 250 of the world’s leading automakers, tier one suppliers and technology companies. The released specifications are the result of the work conducted by numerous technical committees focused on driving interoperability, compliance and testing requirements.

The OPEN Alliance (One-Pair EtherNet) Special Interest Group (SIG) is a non-profit, open industry alliance of mainly automotive industry and technology providers collaborating to encourage wide scale adoption of Ethernet-based networks as the standard in automotive networking applications.
