Opening virtualized networks with O-RAN demands suitable test and measurement solutions
With the technical evolution and motivation of Open RAN, radio access networks (RANs) are made open, disaggregated and intelligent. This technological evolution fosters future RAN to build on virtual network elements, white-box hardware and standardized interfaces. The O-RAN ALLIANCE defines new O-RAN interfaces complementary to 3GPP RAN interfaces and additional specifications, which are used by its members to integrate and test their implementations.
The O-RAN ALLIANCE suggests a double split between the centralized unit (CU) and the distributed unit (DU) as the high layer split (HLS) and defines the low-layer split (LLS) as a fronthaul interface between the O-DU and the radio unit (O-RU). It tackles aspects of user-, control-, management- and synchronization planes.
In collaboration with VIAVI Solutions, Rohde & Schwarz offers a comprehensive suite of O RAN development and conformance test solutions tailored to radio manufacturer needs. These solutions are particularly relevant for those planning to bid for the National Telecommunications and Information Administration (NTIA) Public Wireless Supply Chain Innovation Fund (PWSCIF) Second Notice of Funding Opportunity (NOFO 2), which focuses on open radio commercialization and innovation.
Our solutions encompass the entire product lifecycle and adhere to the specifications set by TIP, 3GPP, O RAN Alliance Working Groups and TIFG. They are designed to help companies launch products on time and within budget. By combining VIAVI's expertise in protocol development and base station emulation with the extensive RF experience of Rohde & Schwarz, these solutions provide robust support for development and manufacturing teams.
