R&S enables Qualcomm to pioneer new frequency ranges for future 5G-Advanced and 6G networks
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. Rohde & Schwarz technology plays a key role in enabling Qualcomm Technologies to show the readiness and effectiveness of the latest RF modem technology for FR3.
At the most recent World Radio Conference 2023, held in November and December 2023 in Dubai, organised 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 has enabled Qualcomm Technologies 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 utilised the R&S SMW200A vector signal generator and R&S FSW signal and spectrum analyser from Rohde & Schwarz. The setup included specialised 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.
Rohde & Schwarz will present its test solutions for the mobile industry including a setup demonstrating high-performance signal generation and analysis for FR3 signals at the Mobile World Congress 2024.
