So whats 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. Theyre 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 its lighter and cheaper

DEVELOPERS, COMPANIES, VENDORS Broadcom showcases connected Car:

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

Its 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.
