vivo selects Keysight’s channel emulation solution for complex 5G device testing, enabling real-world performance verification of smartphones in a lab environment

Beijing, August 6, 2021—Keysight Technologies, a global technology brand, announced today that vivo, has selected the company’s 5G channel emulation solution for complex 5G device testing. Keysight provides advanced design and verification solutions designed to accelerate innovation and create a secure and connected world.

Keysight Technologies' PROPSIM F64 radio frequency (RF) channel emulator, part of the company's channel emulation solution portfolio, was selected by vivo to simulate rural, urban and indoor scenarios in a lab environment and to perform MIMO OTA (over-the-air) testing in this range of scenarios.

"We are pleased to provide vivo with end-to-end repeatable performance testing capabilities in their lab," said Cao Peng, vice president and general manager of Keysight's wireless test business. "Keysight's channel emulation solutions are widely used by leading device manufacturers and network equipment manufacturers to validate the performance of 4G and 5G base station smartphones and tablets before they are released to the market."

Keysight's PROPSIM channel emulation solution enables vivo to test the performance of 5G terminal devices under real channel conditions according to the latest 5G NR specifications defined by 3GPP. Keysight's PROPSIM seamlessly integrates with the UXM 5G wireless test platform to provide CTIA-defined MIMO OTA test cases in FR1. By combining channel and network emulation capabilities, users can also upgrade to more advanced performance testing capabilities, including full-stack end-to-end signaling and radio frequency (RF) performance testing of terminal devices.

"Keysight's test solutions enable vivo to conduct performance testing, supporting our development of innovative technologies that connect consumers around the world," said Xu Mingliang, general manager of hardware and performance testing at vivo. "Our close collaboration with test equipment suppliers enables us to stay at the forefront of 5G and beyond."

vivo uses Keysight's 5G emulation solutions to verify the performance of 5G devices equipped with complex beamforming technologies, such as MIMO and mMIMO in FR1 (below 7GHz). These solutions use real-world complex 3D propagation channels to verify the performance of 5G devices in highly dynamic millimeter wave environments. The integrated test solution enables users to complete baseband modem performance and antenna design performance evaluation from a unified channel emulation platform, thereby reducing test execution time.
