First Interoperability and Data Connection in FR3 Frequency Range

26 August 2024 - Keysight Technologies 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 currently use low to mid-band frequencies within Frequency Range 1 (FR1, 410 MHz to 7.125 GHz) and high-band millimeter wave frequencies in Frequency Range 2 (FR2, 24.25 GHz to 71 GHz). The industry is exploring new upper mid-band frequencies for future 5G Advanced and 6G technologies to support growing high-speed data needs.

A proposed Frequency Range 3 (FR3, 7.125 GHz to 24.25 GHz) offers broad bandwidths and low attenuation, making it a promising option for cost-effective, high-performance future networks.

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.

The Keysight UXM 5G wireless test solution is a highly integrated signaling test platform with multiformat stack support, rich processing power, and abundant radio frequency (RF) resources. Supporting 3GPP Release 15 and beyond, the UXM 5G wireless test solution enables engineers to establish a 5G call with a device under test in different 5G New Radio deployment modes.
