A team of researchers from Germany has set a new world record by transferring the contents of a conventional DVD in under 10 seconds by radio transmission with a data rate of six gigabit per second (Gbps) over a distance of 37 kms. The team achieved the record data transmission on a stretch between Cologne and the 36.7 km distant town of Wachtberg. The extremely high data rate was achieved by the group through efficient transmitters and receivers at a radio frequency of 71-76 GHz in the so-called “E band”, regulated for terrestrial and satellite broadcasting. Researchers from University of Stuttgart and the Fraunhofer Institute for Applied Solid State Physics IAF participated in this collaborative project. The transmission of high quantities of data by radio over large distances serves a high number of important application areas.
