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

Traditional radio access networks (RANs) are gradually moving towards 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 lower and upper physical layers.

Keysight is developing 5G test solutions

This separation allows for the separation of computational tasks and the separation of different components in RAN architectures. O-RUs perform low-level physical layer functions, such as radio frequency (RF) processing, while Open Distribution Units (O-DUs) handle the high-level physical layer and RF characteristics. O-RU vendors previously had to use commercial O-DUs for throughput testing, but 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 real-world O-RU performance without integrating with other vendors' O-DUs. According to the O-RAN Alliance 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 Wireless Test business. "We provide customers with flexible deployment solutions as they commercialize Open RAN.
