Keysight Technologies, Inc. (NYSE: KEYS), a leading technology
company that helps enterprises, service providers and governments
accelerate innovation to connect and secure the world, announced
that the company has contributed to a technical report published by
3GPP on MIMO* over-the-air (OTA) testing that will help the
wireless industry accelerate advanced 5G device performance
validation.
Keysight contributed more than 35 submissions to the technical
report (TR) 38.827 officially approved by 3GPP on July 3rd. This
technical report defines radiated metrics and test methodology for
verifying multi-antenna reception performance of a user equipment
(UE) such as a smartphone or other handheld device operating in
frequency range 1 (FR1) or FR2.
Successful collaboration with the China Academy of Information
and Communications Technology (CAICT) resulted in the first
benchmarking of a 5G 4x4 MIMO device in FR1 using test procedures
and channel models described in 3GPP TR 38.827 and Keysight’s
PROPSIM 5G channel emulator and UXM 5G wireless test platform.
“Thanks to Keysight and other key contributors to the 3GPP MIMO
OTA study item (SI), the industry can effectively benchmark the
performance of 5G devices equipped with various types of antenna
designs and chipsets in a standardized MIMO OTA test environment,”
said Dr. Ruixin Wang, CAICT RAN4 Prime delegate and Rapporteur of
3GPP OTA work items (WIs).
“Keysight is helping a connected ecosystem bring to market
high-performing wireless devices for advanced 5G applications with
a clear understanding of test and measurement complexities shaped
by 5G new radio and supporting technologies such as MIMO,” said
Roger Nichols, 5G program manager and director of wireless
standards at Keysight. “Keysight’s long-standing engagement in the
main wireless standards development organizations (SDOs) and
consortia, combined with a cohesive portfolio of OTA test
solutions, supports the advancement of 5G development and
commercialization around the world.”
This 3GPP milestone supports chipset and device makers in the
process of verifying the performance 5G devices equipped with up to
four antenna transmitters (4x4 MIMO). Keysight contributed by:
- Defining channel models for generating a valid test propagation
environment and the evaluation of test methods for measuring the
data throughput a device transmits.
- Defining MIMO OTA systems to 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
the deliver superior data rates that advanced 5G applications rely
on. Keysight’s new Advanced Performance Test Toolset supports test
cases specified by 3GPP for FR2 MIMO OTA testing, enabling an
expanding ecosystem to validate 5G device performance under
accurate and real-world conditions using 3D fading and mobility
scenarios.
*MIMO (multiple input, multiple output) – an antenna technology
for wireless communications in which multiple antennas are used at
both the source (transmitter) and the destination (receiver).
