Communication and Knowledge – Broadband communications

We can now easily send HD videos, images that are several megapixels big or entire books via data links. It takes just a few minutes for this disparate range of files to end up on the network or on our hard disks. Fraunhofer researchers are working on state-of-the-art broadband transmission, thus laying the foundation for increasingly higher data transmission rates.

Kommunikation und Wissen


Machines communicate by using infrared light

A distinguishing feature of industry 4.0 is the large amount of data generated when production processes are linked. Previously, data streams were sent primarily by cable, but this method is cumbersome when used in industrial processes and the cables are also prone to wear and tear. Transferring data using a wireless LAN is not a viable alternative because it is not fast enough. To solve this problem, engineers at the Fraunhofer Institute for Photonic Microsystems IPMS have developed a module that transmits data rapidly and securely using infrared light.

In the future, people will be able to surf the web using light – quickly, inexpensively, and entirely without radio communication – thanks to a technology Fraunhofer scientists have been researching for years: visible light communication (VLC). This makes commercially available LEDs a viable alternative to conventional wireless network access in situations where radio communication is not desired, or to give people relief from electromagnetic rays and electric smog.

Wireless backhaul technology - WiBack

When fixed line infrastructures are not available to provide backhaul connectivity, wireless links are an option for fast deployment at very low cost. While today's deployments are typically of small size, Fraunhofer's WiBACK Wireless Backhaul Technology targets carrier grade service provisioning in very large wireless networks. Deployment scenarios range from »last-mile« service provisioning in developed countries to wide-area coverage (hundreds of square kilometers) in emerging areas and developing countries.
