Скачать или смотреть ThoR project: Demonstration of bidirectional 300 GHz radio link

Fibre-optic cables are not always the best option when it comes to transmitting data. Especially in cities, it is often not possible to connect every base station of the mobile network by cable. Radio relay links provide an alternative solution. With the help of antennas mounted on roofs, they can bridge distances of up to one kilometre. This creates important backhaul connections between mobile radio cells and the nodes of the mobile radio network without the need for any road construction work. Until now, the high data rates produced by the 5G mobile communications standard, which will continue to increase in the future 6G standard, favoured a fibre-optic connection between stations to the data networks.

The international ThoR project, coordinated by Technische Universität Braunschweig in Germany and Waseda University in Japan with ten other partners from five countries, has now succeeded in developing a bidirectional terahertz radio link that can reliably transmit these high data volumes. The frequency range above 300 gigahertz is used for this as it offers enough spectrum for high data rates. The ThoR-backhaul link is the only one of its kind in the world to offer a bidirectional real data connection and connects TU Braunschweig’s IT centre with the Oker high-rise building over a distance of 160 metres. It can transmit data rates of 2×20 Gbit/s net at a bandwidth of 2×8.64 GHz and is scalable over the bandwidth so that higher data rates can also be realised. In addition, as the first backhaul link of its kind, its functionality also complies with the IEEE 802.15.3 standard. The IEEE 802.15.3 standard was already developed in the run-up to the ThoR project and substantial research contributions were made by TU Braunschweig and several of the Japan-based partners.
