The Rapid Growth of Onboard Ethernet

Ethernet has been widely used in family, school and data centers, and became the most mainstream technical standards of cable transmission in the market. As the widely used of entertainment and other assistant vehicle embedded systems, the demand for on-board network transfer rate gets higher and higher. So vehicle-mounted Ethernet has very big market in the future which attracts many manufacturers,including semiconductor manufacturers.

According to Timothy Lau,car embedded network department director of Broadcom

Car networking development momentum has been overwhelming. There are two applications which havve the strongest demand. One is car infotainment systems, including audio ,video, and navigation.The other is advanced driving assistance systems, including cameras, infrared sensors, ultrasonic sensors. At the same time, growing number of mobile devices, such as mobile phones, tablet computers and cars also drive the car demand for network.　

Timothy Lau thinks the main reason why the onboard Ethernet is favored is that lower cost, lighter weight and higher wire network transmission rate.
