While the new 5G technology is at the first stages of rollout, Rohde & Schwarz, Heinrich Hertz Institute, HHI and the Fraunhofer Institute for Applied Solid State Physics IAF are taking a step further with demonstrations in the terahertz (THz) frequency band, related to the 6th generation wireless mobile communication (6G).
The collaboration has resulted in a wireless transmit and receive system operating between 270 and 320 GHz, with further frequency extensions for potential 6G bands already in preparation.
The utilization of THz frequencies for 6G is estimated to become commercial in the next 8 to 10 years. But Rohde & Schwarz has already presented a demonstrator setup for 300 GHz to customers.
Involved in the current collaboration are the Fraunhofer HHI and the Fraunhofer IAF. The HHI works on signal processing, synchronization between transmitter and receiver, and system integration.
The IAF contributes with high-performance millimeter-wave transmitter and receiver modules. The joint research targets frequencies above 100 GHz, where the primary focus is on the D-band (150 GHz) and the H-band (300 GHz). Carrier frequencies above 300 GHz are still subject of fundamental research.
Dr. Taro Eichler, Wireless Market Segment Manager at Rohde & Schwarz, said, “Rohde & Schwarz offers innovative, top-of-the-line tools for research during the early stages of 6G development. This allows us to engage in in-depth discussions with customers and to monitor the technical and market trends long before the commercialization of 6G. We are excited to partner with Fraunhofer HHI and IAF, benefiting from their leading expertise in development of mobile communication networks and systems, infrastructure and standards. We look forward to a fruitful partnership also in the future.”
Dr. Wilhelm Keusgen, Head of mm-Wave Group at Fraunhofer HHI, said, “As an institution committed to leveraging innovations for the digital society, Fraunhofer HHI is happy to partner with an innovative industry-leading T&M expert such as Rohde & Schwarz on the latest and upcoming communications technologies. Our cooperation has been rewarding and will pave the way for the development of 6G.”
Dr. Michael Schlechtweg, Head of Business Unit High Frequency Electronics at Fraunhofer IAF, said, “As one of the first global providers of chipsets and electronic components capable of reaching already now the high frequencies required by 6G, we are collaborating with valued partner Rohde & Schwarz at the very cutting edge of technology. IAF appreciates the mutually highly beneficial cooperation and is happy to continue exploring new innovations with Rohde & Schwarz.”
