Vivo selected Keysight’s PROPSIM F64 Radio Frequency (RF) Channel Emulator, part of the company’s portfolio of channel emulation solutions, to perform multiple input and multiple output (MIMO) over-the-air (OTA) testing in a laboratory environment.

Vivo is the fifth largest smartphone maker in the world with 10.1 percent share as against 8.6 percent in Q2 2020. Vivo shipped 31.6 million smartphones including 5G smartphones in the second quarter of 2021, according to the latest IDC report.

Cao Peng, vice president and general manager of Keysight’s wireless test group, said: “Major device makers and network equipment manufacturers use Keysight’s channel emulation solutions to verify the performance of 4G and 5G base stations, smartphones and tablets prior to market introduction.”

Keysight said its PROPSIM channel emulation solutions enable vivo to test the performance of 5G devices under real-world channel conditions according to the latest 5G new radio (NR) specifications defined by 3GPP.

Keysight enables vivo to conduct performance testing, supporting the development of our innovative technology that connects consumers around the globe, said Mingliang Xu, general manager of hardware and performance testing at vivo.

vivo uses Keysight’s 5G emulation solutions to validate the performance of 5G devices equipped with beamforming techniques such as MIMO and massive MIMO (mMIMO) in FR1 (sub-7GHz). The solutions use real-world 3D propagation channels to verify the performance of 5G device in dynamic mmWave end-user environments.
