Keysight Technologies has been instrumental in assisting Qualcomm Technologies in achieving the industry’s first end-to-end interoperability and data connection within the FR3 frequency range. This accomplishment was made possible through the use of Keysight’s E7515P UXM 5G Wireless Test Platform alongside Qualcomm’s 5G mobile test platform (MTP).
5G networks are designed to function across three frequency ranges: low-band (FR1), mid-band (FR2), and the newly introduced high-band (FR3). Each range offers distinct advantages, with FR3 enabling wider bandwidths, which facilitate the transmission of large volumes of data at exceptional speeds. The characteristics of FR3 are poised to support 5G-Advanced and 6G use cases, which are expected to transform future wireless communications.
Qualcomm Technologies’ successful FR3 interoperability test involved the calibration of User Equipment and RF Non-signalling verification. This was accomplished using Keysight’s UXM E7515P and VXT3 M9416A, in conjunction with Qualcomm’s Development Acceleration Resource Toolkit (QDART).
Following this, a complete data connection was established to evaluate the potential of using this frequency band for network connections between a 5G base station and a next-generation mobile device. The connection was facilitated by Keysight’s 5G network emulation solutions and Qualcomm’s MTP, a smartphone reference design serving as a proven test device for implementing and validating the latest features developed by Qualcomm Technologies.
The Keysight UXM 5G wireless test solution is an advanced, integrated signalling test platform, offering multiformat stack support, substantial processing power, and extensive radio frequency (RF) capabilities. Supporting 3GPP Release 15 and beyond, the UXM 5G wireless test solution allows engineers to establish a 5G connection with a device under test across various 5G New Radio deployment modes.
Tingfang Ji, Vice President of Engineering at Qualcomm Wireless Research, Qualcomm Technologies, said: “Qualcomm Technologies is grateful for Keysight’s support in assisting Qualcomm Technologies to create ground breaking solutions that empower device manufacturers to accelerate innovations in the next generation of wireless communications. This industry-first milestone will accelerate the design and deployment of the 5G-Advanced and 6G devices.”
Lucas Hansen, Vice President of Keysight’s Wireless Devices and Operators, added: “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 solutions 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 and the time it takes to bring new devices to market.”
