Rohde & Schwarz and Qualcomm unlock potential of proposed FR3 frequency range for next generation 6G wireless networks

Rohde & Schwarz and Qualcomm Technologies, Inc. have demonstrated the feasibility of the proposed FR3 frequency range (7.125 GHz to 24.25 GHz) for future 6G wireless networks. Through their collaborative effort, the two companies successfully validated the performance of Qualcomm Technologies’ 5G mobile test platform (MTP) using the CMX500 5G one-box signaling tester (OBT) in a maximum throughput use case at 13 GHz, a frequency band within the proposed FR3 range. This achievement confirms the potential of FR3 to deliver high data rates utilizing high modulation and coding schemes (MCS) and enhanced capacity leveraging 4x4 MIMO (Multiple-Input Multiple-Output) technology.

The test setup is based on the CMX500 OBT, a future-proof multi-technology, multi-channel one-boxSource: Rohde & Schwarz signaling tester from Rohde & Schwarz. Its versatility allows for easy adaptation to different NR numerologies, making it the ideal choice for FR3 research and development. In this demonstration, the CMX500 OBT is used to:

• Create a signaling environment by transmitting an FR3 cell signal at 13 GHz, simulating real-world conditions.
• Conduct 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, said: “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.”

Tingfang Ji, vice president of engineering at Qualcomm Technologies, Inc., said: “We're excited to have Rohde & Schwarz as a partner in shaping the future of mobile technology. Together, we create groundbreaking solutions that empower device manufacturers to speed up innovations in the next generation of wireless communications, ultimately enriching the mobile experience for users worldwide.”

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, March 3 through March 6 at Fira Gran Via in Barcelona in hall 5, booth 5A80.
