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

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.
