German firm Rohde & Schwarz has performed a channel-sounding measurement marketing campaign with the intention of providing a greater understanding of the properties of electromagnetic wave propagation between 100 GHz and 330 GHz, the corporate stated in a launch.
Rohde & Schwarz famous that the event of sub-THz communications as envisioned for 6G will solely be attainable with a strong understanding of the properties of electromagnetic wave propagation.
Rohde & Schwarz has performed a channel sounding measurement marketing campaign carried out in an city micro situation in addition to an indoor situation at 158 GHz and 300 GHz on the Rohde & Schwarz campus in Munich, Germany.
First outcomes of this marketing campaign have contributed to the ITU-R Working Celebration 5D (W5PD) report on “Technical feasibility of IMT in bands above 100 GHz” with the target to check and supply data on the technical feasibility of cellular mobile applied sciences in bands above 92 GHz, based on the take a look at firm.
The report can be consulted on the Worldwide Telecommunication Union (ITU) World Radio Convention 2023 (WRC23), the place extra frequency bands past 100 GHz are anticipated to be mentioned and thought of for allocation on the subsequent WRC27. The present 3GPP channel mannequin is simply validated as much as 100 GHz. A vital first step for the standardization course of for 6G is to increase this channel mannequin to increased frequencies, the corporate stated.
“We’re proud to contribute our share in investigating THz applied sciences, additional extending information by making use of our modern take a look at and measurement options to early utility situations and elementary analysis, becoming a member of our famend companions such because the Fraunhofer Heinrich Hertz Institute (HHI) and the Technical College (TU) Berlin in collaborations. With our present actions, we lay the inspiration to assist a important step within the standardization means of 6G,” stated Taro Eichler, know-how supervisor at Rohde & Schwarz and accountable for the latest sub-THz measurement marketing campaign.
The German agency additionally stated that the latest measurement marketing campaign is a part of bigger analysis actions with the purpose to raised perceive the millimeter and sub-millimeter (sub-THz and THz) cellular radio channels, which cowl numerous frequencies of relevance for the long run 6G communication customary. To additional pursue and lengthen these analysis actions, Rohde & Schwarz has been granted an experimental license by the German federal community company Bundesnetzagentur to increase analysis actions. The license encompasses frequencies within the sub-THz area such because the D-band (110 GHz – 170 GHz) and H-band (220 GHz – 330 GHz), but additionally within the W-band (75 GHz – 110 GHz), FR2 (mmWave), FR3 (7 GHz – 24 GHz) and the economic frequency band in Germany, 3.7 GHz – 3.8 GHz.
