Fraunhofer HHI shows an optical LiFi solution for reliable wireless communication

19.04.2016

Reliable low latency wireless M2M communication is essential for the success of Industry 4.0. The Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI offers an innovative optical wireless communication (LiFi) solution for secure data exchange and robust links. This technology can be seen in action at the Fraunhofer booth C16/22 in Hall 2 during the Hannover Messe.

Nowadays, high-tech products such as cars are tailor-made fabricated to specific customer demands. Satisfying the diverse demands requires flexible and quickly configurable manufaction. To achieve this flexibility in future manufacturing processes, fixed (“wired”) links must be replaced with wireless communication systems.

Currently, most manufacturers use WiFi connectivity in their production lines. However, interference with WiFi transmissions is even possible through walls. This increases the risk of partial or complete production downtimes. Furthermore, the allotted radio frequencies are already crowded by diverse implementations requiring the transmission of large data volumes.

The optical wireless communication (OWC) technology engineered by Fraunhofer HHI, also known as LiFi, serves as flexible connectivity solution for use in industrial environments.

This innovative technology creates additional not yet exploited bandwidth in the visible spectrum, which is not subject to licensing. LiFi creates the basis for many attractive and useful implementations.

Dominic Schulz M. Eng., project manager at Fraunhofer HHI, points out: ”Using light as communication medium is a fascinating solution because there is little interference with existing technologies. We are convinced that we can efficiently use LiFi to meet many wireless communication requirements in business environments.”

Currently, the Institute of Electrical and Electronics Engineers (IEEE) creates new standards and protocols for LiFi as new mobile connectivity technology, which can be applied in industrial use-cases, as well.

As part of the initiative 'Zuverlässige drahtlose Kommunikation in der Industrie (ZDKI) / Reliable Wireless Communication in Industry' the German Federal Ministry of Education and Research (BMBF) funds the project 'Optical Wireless Networks for Flexible Car Manufacturing Cells' (OWICELLS).

In this project, Fraunhofer HHI, the BMW Group as well as the EVOPRO and OSRAM Companies jointly explore and test innovative concepts of fostering the deployment of optical wireless technologies for industry. The goal is to apply MIMO concepts (multiple input multiple output) for the creation of robust communication links even in cases of line-of-sight interruption.

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
