R&S probes sub-THz channel measurements for 6G

The development of sub-THz communication as envisioned for 6G is the focus of a measurement campaign conducted by Rohde & Schwarz. Sub-THz typically spans the frequency range from 100 GHz to 330 GHz and represents one potential building block of a future 6G wireless communication standard. To fully exploit the technology’s potential, it is crucial to understand the electromagnetic wave propagation characteristics of THz frequencies by performing channel sounding measurements.

R&S conducted a channel sounding measurement campaign performed in an outdoor urban environment, as well as an indoor scenario, at 158 GHz and 300 GHz. Findings of this campaign have contributed to the ITU-R Working Party 5D (W5PD) report, which will provide information to the International Telecommunication Union (ITU) World Radio Conference 2023 (WRC23).

Additional frequency bands beyond 100 GHz are expected to be discussed and considered for allocation at the subsequent WRC27. The current 3GPP channel model is only validated up to 100 GHz. A crucial first step for the standardization process for 6G is to extend this channel model to higher frequencies.

Further information and results of the R&S measurement campaign are available in the white paper, Fundamentals of THz technology for 6G. Registration is required for downloading.
