This layer is ideal for high-bitrate data transmission used in driver assistance systems, for connecting mobile devices, and for in-vehicle multimedia applications. Here's
an example of what driving could be like in the future: The driver can relax while the car navigates through rush hour traffic using its camera-based assistance systems. Simultaneously, passengers can watch a live sporting event streamed via internet TV on the car's entertainment system. Tomorrow's sporting events will be broadcast in 4K quality from every conceivable angle.
The 10+ Gbit/s physical layer accelerates fixed-line telephony data transmission.
These parallel applications require high data throughput over a simple, lightweight, and low-cost copper cable, combined with low power consumption and minimal latency. Fraunhofer IIS has developed this foundational technology for the next generation of data transmission and is in the process of bringing it to production readiness. Consuming less than one watt per transmitter/receiver pair, the new physical layer can transmit 10 Gbit/s over a single 10-15 meter long twisted-pair cable. Keeping latency to a minimum, it provides video data for real-time human-machine interaction tasks. The universal design of this development allows a wide range of content with various requirements to be transmitted simultaneously, meaning that connections that previously operated in parallel can now operate over a single pair of wires.
The physical layer currently operates at 10 Gbit/s. For other applications, the goal is to increase the data rate to 12.5 Gbit/s. This will serve as the core technology for virtually all common data rates of 10 Gbit/s and higher.
Applications range from mechanical engineering to broadcasting. High-speed data transmission systems are by no means limited to the embedded electronics of a vehicle. Many other application areas have similar requirements. These areas include industrial facilities, mechanical and systems engineering, automation technology, medical technology, robotics, and data centers. Broadcasting using multiple cameras and HD or even 4K video streaming can benefit from this technology.
Scientists from Fraunhofer IIS will be demonstrating an evaluation and testing platform for the 10+ Gbit/s physical layer in Hall A, Stand 113.
