The current models feature multiple communication systems that connect the engine, drivers assist, tire pressure, airbag and safety systems and camera/radar systems to the drivers display. There is also a network that connects the passenger area to the information system along with entertainment control. These systems are moving from just wired systems like CAN, MOST, and Flexray to more standard systems like Ethernet. These a new wired Ethernet solutions can support low weight, unshielded cable capable of 100Mbps in full duplex mode, for connectivity. This wired core system is being sought by many auto manufacturers, such as BMW, to allow for the car being a platform core, like a data center, with one in-platform interconnect system, and edge of network being wireless or USB interface. The wireless connections of choice are WiFi and Bluetooth both sharing the 2.4GHz band.
