FR3 Frequency Range Achieves First Interoperability and Data Connection

5G networks are paving the way for a new era of wireless communications, offering enhanced capabilities and faster speeds. These networks are designed to operate in three frequency ranges: low-band (FR1), mid-band (FR2), and the newly introduced high-band (FR3). Among these, FR3 stands out for its wider bandwidths, enabling the transmission of large amounts of data at incredibly high speeds. This unique property positions FR3 to support 5G-Advanced and even future 6G use cases that have the potential to revolutionize the way we communicate wirelessly.

Qualcomm Technologies recently conducted a successful FR3 interoperability test, focusing on User Equipment calibration and RF Non-Signaling verification. Leveraging the Keysight UXM E7515P and VXT3 M9416A, along with Qualcomm’s Development Acceleration Resource Toolkit (QDART), the test demonstrated the feasibility of utilizing the high-band frequency for network connections between a 5G base station and next-generation mobile devices. This milestone marks a significant step towards realizing the full potential of FR3 in advancing wireless technologies.

The Keysight UXM 5G wireless test system plays a crucial role in enabling these advancements. With its highly integrated signaling test platform, multiformat stack support, and abundant RF resources, the UXM system supports 3GPP Release 15 and beyond. Engineers can leverage this system to establish 5G calls with devices under test in various 5G New Radio deployment modes, facilitating comprehensive testing and validation processes.

Lucas Hansen, Vice President of Keysight's Wireless Devices and Operators, emphasized the importance of collaboration in driving innovation. He stated, “In our support of Qualcomm Technologies, Keysight is expediting the market entry of next-generation mobile devices through an industry-first FR3 data connection. Keysight’s cutting-edge emulation products uniquely enable chipsets and device makers to validate their devices for the new era of technology. This achievement will accelerate the 5G-Advanced and 6G device design cycle, reducing the time it takes to bring innovative devices to market.”

As the industry continues to push the boundaries of wireless communications, the successful integration of FR3 into 5G networks opens up a world of possibilities for future technologies. With companies like Qualcomm Technologies and Keysight leading the way in testing and validation, we can expect to see rapid advancements in mobile devices and network capabilities, ultimately shaping the way we connect and communicate in the years to come.
