Keysight has contributed more than 35 documents to technical report (TR) 38.827 Officially approved by 3GPP on July 3rd, this technical report defines the radiation testing metrics and methodology for verifying the reception performance of multi-antenna user equipment (UE), such as smartphones or other handheld devices operating in frequency range 1 (FR1) or FR2.
The successful collaboration with the China Academy of Information and Communications Technology (CAICT) has resulted in the first performance test on a 5G 4x4 MIMO device in FR1 using test procedures and channel models described in 3GPP TR 38.827 together with the PROPSIM 5G channel emulator and the Keysight UXM 5G wireless test platform.

“Keysight is helping the connected ecosystem bring high-performance wireless devices to market for advanced 5G applications with a clear understanding of the measurement and testing complexities posed by the new 5G radio and supporting technologies like MIMO,” said Roger Nichols, 5G Program Manager and Director of Wireless Standards at Keysight. “Keysight’s long-standing involvement in leading Standards Development Organizations (SDOs) and consortia, combined with a unified portfolio of OTA testing solutions, supports the advancement of 5G developments and their commercialization worldwide.”
This 3GPP milestone supports chipset and device manufacturers in the process of verifying the performance of 5G devices equipped with up to four transmitting antennas (4x4 MIMO). Keysight contributed by:
• Defining channel models to generate valid tests in a propagation environment and evaluating test methods for measuring the data rate transmitted by a device.
• Defining MIMO OTA systems that ensure repeatability and stability in test results.
Keysight offers a wide range of test platforms for verifying 5G devices that use MIMO technology and high-performance antennas to deliver the superior data rates required by advanced 5G applications. Keysight’s new Advanced Performance Testing Toolkit supports 3GPP-specified test cases for FR2 MIMO OTA testing, enabling the expanding ecosystem to validate 5G device performance under precise, real-world conditions using three-dimensional fading mobility scenarios.

*MIMO (multiple input, multiple output) – is an antenna technology for wireless communications in which multiple antennas are used at both the source (transmitter) and the destination (receiver).
