High-Speed Data Transmission for Next Generation Automotive Networks

Multi-Gigabit Links for Next Generation Automotive Networks


Data transmission speeds are rapidly increasing, due largely to high-resolution video data applications. Although the automotive sector still relies primarily on 1 Gbit solutions, industry experts are already discussing the possibility of 12 Gbit alternatives for driving high-resolution 4K displays.

Reliably and cost-effectively transmitting data at such high rates requires optimizing the entire transmission system. System design begins with the selection of a suitable modulation format and the occupied channel bandwidth, plus the cables and plugs that will be utilized.

With this workshop, Fraunhofer IIS aims to enhance and further stimulate current discussions regarding future high-speed data transmission links. In the first part of the workshop, end users - automobile manufacturers and suppliers - have been invited to outline the demand for vehicle data transmission applications. Various solutions designed to address this need will then be put forward and discussed among the participants.

Since data transmission solutions are typically not viewed as unique selling points in the automobile industry, an open discussion of the issues can be expected. For tier 1 and tier 2, the workshop should provide valuable information regarding further development trends. A small area for showing demos and exhibiting posters will be available.
