Keysight and Metanoia Confirm 5G Low Physical Layer Conformance of Open Radio Block

Báo Thanh niênBáo Thanh niên14/11/2023


Traditional radio access networks (RANs) are gradually transforming to more open, intelligent, and virtualized architectures. To achieve this goal, the physical layer of the OPEN RAN architecture is developed on the basis of separating functions into low and high physical layers.

This separation allows for the separation of computational tasks and the separation of different components in 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 the high-level physical layer and RF characteristics. O-RU vendors previously had to use commercial O-DUs for throughput testing, but the test results were affected because commercial O-DUs had their own performance implications.

Using Keysight’s Open RAN Studio solution, Metanoia successfully performed uplink and downlink throughput measurements. O-DU emulation enables Keysight’s Open RAN Studio to extend the measurement scope to verify the real-world performance of the O-RU without integrating with other vendors’ O-DUs. According to the O-RAN A LLIANCE specification, Open RAN Studio enables Metanoia to validate RF characteristics and bandwidth performance. The solution is part of Keysight’s comprehensive Open RAN Architecture (KORA), a portfolio of test solutions for Open RAN equipment, software, and interfaces.

“Keysight continues to accelerate Open RAN deployment projects by enabling O-RU manufacturers to validate their designs with innovative test solutions,” said Peng Cao, vice president and general manager of Keysight’s Radio Test Group. “We provide customers with flexible deployment solutions as they commercialize Open RAN.
