Rohde & Schwarz, a globally active and leading T&M specialist, in association with VIAVI Solutions, a leading provider of communications test, measurement and optical technologies, has supported the European OTIC in Berlin in awarding O-RAN conformance certification for international markets. The certification of an indoor O-RU of the LPRU series from VVDN Technologies was completed according to O-RAN specified processes and procedures defined by the O-RAN ALLIANCE. This marks the first certification accomplished by a European test lab.
The i14y Lab is an open lab for interoperability testing of disaggregated telco systems, such as open RAN, led by Deutsche Telekom together with consortium partners. The test and measurement expert Rohde & Schwarz is one of the consortium members and offers an integrated solution for conformance testing of O-RAN Radio Units together with VIAVI Solutions. Both companies are active in specifications development in the O-RAN ALLIANCE and have combined their industry-leading capabilities: The solution consists of the VIAVI TM500 O-RU Tester and the R&S SMBV100A vector signal generator (VSG), R&S FSVA3000 signal and spectrum analyzer and Vector Signal Explorer (R&S VSE) software from VIAVI TM500, with the O-RU Test Manager from VIAVI as single point of control, providing a seamless user experience.
All approved Open Testing and Integration Centers (OTIC) worldwide cooperate with the O-RAN ALLIANCE in the O-RAN Certification and Badging Program, which represents a comprehensive mechanism to ensure confidence in O-RAN solutions within the industry. O-RAN is making radio access networks more open, disaggregated and flexible. Opening the network architecture can foster innovation, accommodate individual needs and enhance network efficiency. Therefore, O-RAN is experiencing rapid advancement and growth in the technology ecosystem.
VVDN Technologies has developed the LPRU-series 5G NR Radio Units (O-RU) to comply with O-RAN ALLIANCE standards fully. The VVDN 4T/4R Split 7.2 radios are covering 5G NR TDD bands n77, N78 and n79. They are compact, lightweight, easy to install, and provide optimal coverage for indoor applications. The design has completed the extensive 3GPP and O-RAN compliance testing.
The O-RU verification followed the O-RAN fronthaul conformance test specification defined by O-RAN WG4, including the Control, User, and Synchronization plane (CUS-Plane) and the Management-plane (M-Plane). WG4 aims to deliver open fronthaul interfaces, in which interoperability between Distributed Units (DU) and Radio Units (RU) from multiple vendors can be realized.
