Keysight Establishes First Interoperability and Data Connection in FR3 Frequency Range

08/18/2025

Keysight Technologies, Inc. played a key role in enabling Qualcomm Technologies, Inc. to make the industry’s first end-to-end interoperability and data connection in the FR3 frequency range using the Keysight E7515P UXM 5G Wireless Test Platform and a 5G Qualcomm Technologies mobile test platform (MTP).

5G networks are designed to operate in three frequency ranges: low-band (FR1), mid-band (FR2), and the newly introduced high-band (FR3). Each frequency offers specific advantages for 5G services, with FR3 providing wider bandwidths enabling the transmission of large amounts of data at very high speeds. These unique properties will allow FR3 to support 5G-Advanced and 6G use cases that promise to revolutionize future wireless communications.

Qualcomm Technologies’ successful FR3 interoperability test encompassed User Equipment calibration and RF Non-signaling verification. This was achieved using Keysight UXM E7515P and VXT3 M9416A, facilitated by Qualcomm’s Development Acceleration Resource Toolkit (QDART). Finally, a full-stack data connection was established to assess the feasibility of utilizing the frequency band for network connections between a 5G base station and a next-generation mobile device. The connection was made using Keysight’s 5G network emulation solutions and the Qualcomm Technologies MTP, a smartphone reference design that acts as a proven test device for implementing and verifying the most advanced device features available from Qualcomm Technologies research labs.
