Qualcomm teams to open up 5G-Advanced and 6G frequencies
Rohde & Schwarz has been working with Qualcomm Technologies on a Giga-MIMO system for 5G-Advanced and 6G networks in new frequency bands.
The 6G Giga-MIMO system uses ten times the number of antennas for wide-area coverage in 7 to 16 GHz bands, and to validate the performance of the prototype system, Qualcomm Technologies used a new vector signal generator and 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.
“Our efforts to enable Giga-MIMO in upper midband for wide-area coverage help to set the stage for 6G and a transformative leap in wireless communication,” said Tingfang Ji, Vice President of Engineering at Qualcomm Wireless Research
In the evolving landscape of 5G networks, leveraging frequency ranges FR1 (0.41 to 7.125 GHz) and FR2 (24.25 to 71 GHz) has been pivotal. As the era of 5G-Advanced and 6G unfolds, a third frequency range is being discussed in global regulatory and industry consortiums worldwide.
FR3, which is also known as upper-midband, spanning 7.125 to 24.25 GHz, will open a new frontier for mobile communication technology.

IMT-2030, also known as 6G, is opening up the 14.8 to 15.35 GHz frequency range globally while local agencies like the Federal Communications Commission (FCC) in the US are also eyeing the upper 12 GHz band (12.7 to 13.25 GHz) for future wireless applications.
“Our tailored test solutions are instrumental in advancing research for 5G-Advanced and 6G networks, and exploring the possibilities of the FR3 frequency range lays the foundations for the success of tomorrow’s mobile applications,” said Andreas Pauly, Chief Technology Officer at Rohde & Schwarz.
At MWC Barcelona later this month, Rohde & Schwarz will demonstrate a high performance signal generation and analysis setup for early FR3 research, featuring the latest vector signal generator and analyzer products.

The setup consists of the R&S SMW200A, not only with a new front panel and user interface but also significant improvements in EVM performance. On the analysis side, the R&S FSVA3000 includes special features like IQ noise cancellation to achieve outstanding EVM measurement performance thanks to a noise corrected measurement path. Dedicated 5G signals for FR3 are being generated and analyzed as part of the demonstration.
