Efficient Networks in Vehicles for Data Rates up to 12.5 Gbit/s
Using the 10+ Gbit/s physical layer for a simple twisted pair wireline data transmission, it is possible to transfer data at rates of 10 Gbit/s in real time. The new high-speed is ideal for high-bit-rate data streaming with real time requirements used in driver assistance systems with machine vision, but also for connecting mobile devices as well as for multimedia applications in vehicles.
These applications require high data throughput using a simple, lightweight and inexpensive copper cable, combined with low power consumption and minimum latency. Consuming less than one watt for every transmitter/receiver pair, the new physical layer can transmit 10 Gbit/s over a single twisted pair cable 10–15 meters long. Keeping the latency to a minimum provides video data for machine vision applications and human-machine interaction tasks in real time. The universal design of this development allows a wide range of content with various requirements to be transmitted effective simultaneously, which also means that connections that used to run in parallel can now be consolidated into one pair of wires. The developed physical layer is currently working at 10 Gbit/s. For further applications a data rate of 12.5 Gbit/s is being developed.
Similar requirements are found in production automation and robotics, i.e. in the field of environment detection and material testing, as well as at medical technology. Broadcasting that uses multiple cameras and HD or even 4k video streaming can also benefit from this technology.
Fraunhofer IIS scientists will be demonstrating an evaluation and test platform for the 10+ Gbit/s physical layer at embedded world (Hall 4, Booth 4-460) from February 27 to March 1, 2018.
