Keysight and Cambridge Industries Complete Interoperability Testing of O-RAN Radios

Aug. 5, 2020
As a result, CIG and other vendors of O-RUs can accelerate design verification of products based on specifications set by the O-RAN Alliance.

Keysight Technologies announced interoperability development testing (IODT) of O-RAN radio units (O-RUs) in collaboration with Cambridge Industries Group (CIG), an original design manufacturer (ODM), headquartered in Shanghai, China. The testing was accomplished using CIG's O-RU and Keysight's Open RAN Studio, signal source and analyzer solutions to create an environment for 5G new radio (NR) modulation analysis.

As a result, CIG and other vendors of O-RUs can accelerate design verification of products based on specifications set by the O-RAN Alliance. CIG is part of a network infrastructure ecosystem that is using O-RAN fronthaul interfaces to unlock the full potential of an open RAN architecture.  

"We rely on partners such as Keysight to effectively develop and validate open RAN standards-based network elements, including small cells and O-RAN compliant radio and distributed units," said Haibo Zhao, founder, chief technology officer (CTO) at CIG. "This enables CIG to derive insights critical in the design and manufacturing of a flexible infrastructure that serves diverse use-cases for consumers and vertical industries." 

Keysight, the first test vendor to launch O-RAN distributed unit (O-DU) emulation software for validating O-RAN compliant O-RUs, has helped speed development of conformance validation and verification of interoperability between O-RUs and O-DUs. Keysight's Open RAN Studio integrates with the company's PathWave signal generation and vector signal analysis (VSA) software for advanced modulation analysis of signal and radio performance.
