The latest World Radio Conference 2023, organized and organized by the International Telecommunication Union (ITU) and held in Dubai in November and December 2023, will bring together regulators and industry leaders to discuss additional spectrum for next-generation mobile communications. A consensus was reached to consider it. , officially labeled IMT-2030 and also known as 6G. In particular, the frequency range from 14.8 to 15.35 GHz has been allocated for worldwide research. In addition, local agencies such as the Federal Communications Commission (FCC) in the United States are also eyeing the upper 12 GHz band (12.7-13.25 GHz) for future wireless applications.
Anticipating these developments, Rohde & Schwarz, a leading supplier of test and measurement solutions to the wireless industry, announced that Qualcomm Technologies, a pioneer in wireless systems technology, is making Giga-MIMO systems ready for tomorrow’s infrastructure. We have made it possible to demonstrate that it is possible and effective. It operates on these frequencies. Currently operating at 3.5 GHz, it promises improved data performance while offering coverage comparable to 5G Massive MIMO networks.
To verify the performance of this prototype, Qualcomm Technologies utilized a Rohde & Schwarz R&S SMW200A vector signal generator and R&S FSW signal and spectrum analyzer. This setup included specialized firmware to test different subcarrier spacings, with wider signal bandwidth compared to today’s 3GPP physical layer specifications. More bandwidth ultimately results in higher data rates and lower latency.
Andreas Pauly, Chief Technology Officer of Rohde & Schwarz, said: Our customized test solutions help advance research in 5G-Advanced and 6G networks, and exploring the potential of the FR3 frequency range lays the foundation for the success of tomorrow’s mobile applications. ”
Tingfang Ji, Vice President of Engineering, Qualcomm Wireless Research, Qualcomm Technologies. Our efforts to enable Giga MIMO in the upper midband for wide area coverage will help set the stage for a transformative leap forward in 6G and wireless communications. ”
FR3 signal generation and analysis demonstration at MWC Barcelona
At MWC Barcelona, 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 latest R&S SMW200A with a new front panel and user interface as well as significantly improved EVM performance. On the analysis side, the R&S FSVA3000 incorporates special features such as IQ noise cancellation, which provides superior EVM measurement performance with a noise-compensated measurement path. His 5G signal dedicated to FR3 is being generated and analyzed as part of the demonstration.
Rohde & Schwarz will be showcasing comprehensive test solutions for the mobile industry at Mobile World Congress 2024, including a setup demonstrating high-performance signal generation and analysis of FR3 signals. Visitors can find Rohde & Schwarz in Fira, Hall 5, Booth 5A80. Gran Via in Barcelona.
