Traditional radio access networks (RANs) are gradually transitioning to more open, intelligent, and virtualized architectures. To achieve this goal, the physical layer of the OPEN RAN architecture is developed by separating functions into low-level and high-level physical layers.
Keysight is currently developing 5G measurement and testing solutions.
This separation allows for the partitioning of computational tasks and the separation of different components within RAN architectures. The O-RU performs low-level physical layer functions, such as radio frequency (RF) processing, while the Open Distribution Unit (O-DU) handles high-level physical layer processing and RF characteristics. O-RU vendors previously had to use commercial O-DUs in throughput testing; however, test results were affected because commercial O-DUs have their own performance impacts.
Using Keysight's Open RAN Studio solution, Metanoia successfully performed uplink and downlink throughput measurements. O-DU emulation allowed Keysight's Open RAN Studio to extend the measurement range to verify the actual performance of O-RUs without integrating with O-DUs from other vendors. According to the O-RAN Alliance specifications, Open RAN Studio enabled Metanoia to validate RF characteristics and bandwidth performance. This solution is part of Keysight's comprehensive Open RAN Architecture (KORA), a portfolio of measurement solutions for Open RAN devices, software, and interfaces.
Peng Cao, Vice President and General Manager of Keysight's Radio Measurement division, said: "Keysight continues to accelerate Open RAN deployments by enabling O-RU manufacturers to validate their designs with innovative measurement solutions. We provide our customers with flexible deployment solutions during the commercialization of Open RAN."
