So what’s old is new again..

Ethernet will connect all relevant ECUs, antennas and sensors

The new local area networking technology for cars

Reduce the complexity and cost of wiring your ride

Average cars have few miles’ worth of cables and wires

They control your anti-lock braking system

Currently use low-voltage differential signaling (LVDS) cabling

Cables are efficient and reliable. They’re also heavy and expensive

Benefits

Building more connectivity without increasing weight

Less weight, Less fuel consumption

Car will be like your living room on the go – cameras and entertainment, diagnostics and safety

Enables the data exchange between computers and electronic devices

Some Drawbacks

Gathering the real-time requirements of various time-critical car applications Standard Ethernet does not provide any quality-of-service guarantee on the bandwidth, thus one should be careful not to miss any hard deadlines of message delivery

Low-Cost

Low-cost tools from PC and industrial Ethernet equipment already on the market

Reduce connectivity costs by 80% and cabling weight by 30% because it’s lighter and cheaper

DEVELOPERS, COMPANIES, VENDORS

Into The Future

Future use of Ethernet will be requested and desired

By around 2020, many innovators estimate there will be about 100 million Ethernet ports worldwide in automobiles

Electronic features is growing!

Possible BarriersThe number of features and bandwidth required will be cheaper to "start again" with an Ethernet backbone-type architecture.Already met rigorous automotive industry standards

It’s about time

Turn-by-turn navigation, the front-seat passenger can stream music from the Internet, and each backseat passenger can view different videos on their individual displays

without compromising the quality of any of these data streams flowing across the Ethernet network.
