Proposed FR3 frequency range validated for 6G networks

Rohde & Schwarz and Qualcomm Technologies have joined forces to showcase the potential of the proposed FR3 frequency range for future 6G wireless networks. This frequency range spans from 7.125 GHz to 24.25 GHz, offering a wide spectrum for high-speed data transmission and enhanced network capacity.

The collaborative effort between the two companies focused on validating 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 FR3 range. This successful test confirmed the capability of FR3 to support high data rates through advanced modulation and coding schemes (MCS) and 4x4 MIMO technology.

One of the key components in expediting the development process is the 5G MTP, which serves as a smartphone reference design for verifying and implementing new features. It plays a crucial role in ensuring device compliance with the latest 3GPP Release 17 standards, paving the way for seamless integration of cutting-edge technologies.

The test setup utilized the CMX500 OBT multi-channel one-box signalling tester from Rohde & Schwarz, known for its adaptability to different NR numerologies. This flexibility makes it an ideal tool for research and development activities related to the FR3 frequency range, enabling researchers to explore various scenarios and optimize network performance.

During the demonstration, the CMX500 OBT was employed to create a realistic signalling environment by transmitting an FR3 cell signal at 13 GHz. This simulation provided valuable insights into the device's ability to achieve maximum throughput within the FR3 frequency range, ensuring reliable and efficient operation under real-world conditions.

Christoph Pointner, Senior Vice President of Mobile Radio Testers at Rohde & Schwarz, expressed enthusiasm about the collaboration with Qualcomm Technologies, emphasizing the importance of joint innovation in driving the evolution of wireless communication technologies. The partnership aims to accelerate the development of next-generation 6G technologies, pushing the boundaries of what is achievable in the realm of wireless networks.

Looking ahead, Rohde & Schwarz and Qualcomm Technologies are set to present a high-performance setup for early FR3 research at the upcoming Mobile World Congress 2025. The showcase will feature the CMX500 OBT as a key enabler for exploring the capabilities of the FR3 frequency range and demonstrating the potential for future advancements in wireless communication.
