Rohde & Schwarz enables Qualcomm to pioneer new frequency ranges for future 5G-Advanced and 6G networks

03/20/2024

At the most recent World Radio Conference 2023, held in November and December 2023 in Dubai, organized and hosted by the International Telecommunication Union (ITU), a consensus emerged among regulatory bodies and industry leaders to explore additional spectra for the next generation of mobile communication, officially labeled IMT-2030, also known as 6G. Notably, the 14.8 to 15.35 GHz frequency range has been earmarked for global study. In addition, local agencies like the Federal Communications Commission (FCC) in the United States are also eyeing the upper 12 GHz band (12.7 to 13.25 GHz) for future wireless applications.

In anticipation of these developments, Rohde & Schwarz, leading supplier of test and measurement solutions to the wireless industry, has enabled Qualcomm Technologies, a trailblazer in wireless system technology, to demonstrate that the Giga-MIMO system for tomorrow’s infrastructure is ready and effective to operate in these frequencies. It promises enhanced data performance while offering coverage comparable to current 5G massive MIMO networks operational at 3.5 GHz.

To validate the performance of this prototype, Qualcomm Technologies utilized the R&S SMW200A vector signal generator and R&S FSW signal and spectrum analyzer from Rohde & Schwarz. The setup included specialized firmware for the testing of different subcarrier spacings with wider signal bandwidths compared to today's 3GPP physical layer specifications. The wider bandwidths will ultimately enable higher data rates and lower latency.
