Proposed FR3 frequency range validated for 6G networks
Rohde & Schwarz and Qualcomm Technologies have demonstrated the feasibility of the proposed FR3 frequency range for future 6G wireless networks. The range covers 7.125 GHz to 24.25 GHz.
The collaborative effort validated the performance of Qualcomm Technologies’ 5G mobile test platform (MTP) using the CMX500 5G one-box signalling tester (OBT) in a maximum throughput 5G NR use case at 13 GHz, a frequency band within the proposed FR3 range. This confirms the potential of FR3 to deliver high data rates utilising high modulation and coding schemes (MCS) and enhanced capacity leveraging 4×4 MIMO technology.
Speeding up development, the 5G MTP is a smartphone reference design that helps verify and implement new features. It also ensures device compliance with 3GPP Release 17.
The test setup is based on the CMX500 OBT multi-channel one-box signalling tester from Rohde & Schwarz. Its versatility allows for easy adaptation to different NR numerologies, making it the ideal choice for FR3 research and development.
The demonstration used the CMX500 OBT to create a signalling environment by transmitting an FR3 cell signal at 13 GHz, simulating real-world conditions. The CMX500 OBT also provided comprehensive analysis, verifying the device’s ability to achieve maximum throughput in the FR3 frequency range, ensuring reliable and efficient operation.
Christoph Pointner, Senior Vice President of Mobile Radio Testers at Rohde & Schwarz, says: “Our collaboration with Qualcomm Technologies demonstrates the power of joint innovation. Together, we’re accelerating the development of tomorrow’s 6G technologies, pushing the boundaries of what’s possible in wireless communication.”
Rohde & Schwarz and Qualcomm Technologies will jointly showcase a high-performance setup for early FR3 research featuring the CMX500 OBT at Mobile World Congress 2025.
