Researchers of the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have achieved wireless transmission of 40 Gbit/s over a distance of one kilometer, a new world record.

The technology may help provide future broadband access to the Internet in rural areas and places which are difficult to access.

Using a high frequency range between 200 and 280 GHz enables the fast transmission of large volumes of data and compact equipment. The design also allows for compatibility with fiber optic cables.
