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.

Projects

  • Faster video streaming

    In the smartphones and tablet era, more and more users are watching videos on the move – with a resulting strain on mobile networks. The combination of the HEVC video compression standard with LTE brings networks welcome relief.

  • New standard HEVC encodes films more efficiently

    Television resolution is constantly improving – and this must go hand-in-hand with transmitting the data more efficiently. Reputable manufacturers of televisions, computers and mobile telephones, working jointly with Fraunhofer researchers, are developing a new standard for data transmission: “High Efficiency Video Coding”, or HEVC for short. This video codec was unveiled in Amsterdam at the IBC trade show.

  • Judder-free videos on the smartphone

    Overloaded cellular networks can get annoying – especially when you want to watch a video on your smartphone. An optimised Radio Resource Manager will soon be able to help network operators accommodate heavy network traffic.

  • Jointly utilizing LTE networks

    Data-intensive Internet applications on smartphones, tablets and laptops are more popular than ever before. The result: Traffic on the mobile network is increasing at a blinding speed. Intelligent technologies are intended to increase the data rates on the new LTE network. The solution is to use the mobile networks jointly.

  • Data are traveling by light

    Regular LEDs can be turned into optical WLAN with only a few additional components thanks to visible light communication (in short, VLC). The lights are then not just lighting up, they also transfer data. They send films in HD quality to your iPhone or laptop, with no loss in quality, quickly and safely.

  • A world record in serial data transmission via fiber optics – 10.2 Tb/s or an astonishing 240 DVDs per second

    In a new world premier, members of Berlin’s Fraunhofer Heinrich Hertz Institute in collaboration with the Technical University of Denmark in Copenhagen have succeeded in generating a serial data rate of 10.2 Terabit per second and transmitting it over a 2 9 km long fiber optic link.

  • 3-D Films on Your Cell Phone

    3-D-Filme auf dem Handy

    Researchers at Fraunhofer have combined the new mobile radio standard LTE-Advanced with a video coding technique. This puts 3-D films on your cell phone. The experts will be presenting their solution from February 14-17 in Hall 2, Stand E41 at the Mobile World Congress in Barcelona.
