THz

In 1895, the Italian radio pioneer and company founder Guglielmo Marconi succeeded in transmitting radio waves over several kilometers with frequencies in the kHz range. kHz radio waves are used today for radio navigation and for long- and medium-wave broadcasting.
In 1923, the first radio communication across the Atlantic with short waves in the MHz range was successful, and the first radio transmissions followed in 1925. Today, MHz radio waves are used for terrestrial television and radio transmission with short and ultrashort waves.
In 1991, the first wireless GHz system was demonstrated as the second generation (2G) of mobile communication, and the first cell phones became available one year later. Further evolutions from the first WLAN/WiFi standard in 1997, 3G in 2001, 4G in 2009, and 5G today are all based on GHz radio waves.
In ~2030, 6G will likely integrate THz technology at its core, not only due to its enormous bandwidth but also its multidisciplinary opportunities: Communication will be associated with Imaging, Material Characterization, Localization, and Radar systems, enabling a novel sensing of the environment and therefore making stunning applications such as a “3D Cleaning and Sorting Household Robot” or “High-Fidelity Mobile Holograms” feasible.
DSV’s overall THz expertise is based on one 6-year collaborative project on THz communication and a Collaborative Research Center "MARIE" (see www.trrmarie.de ) on THz Material Characterization and Localization started on Jan. 1, 2017.
