Innovative solutions for O-RAN test and measurement
The evolution of Open RAN (O-RAN) is making radio access networks (RAN) more open, disaggregated and flexible. Opening the network architecture can foster innovation, enable customization to individual needs and enhance network efficiency.
Interface standardization allows a network to mix and match vendors. However, this introduces new challenges in ensuring interoperability between network components. As such, advanced equipment is key for the development, certification and regression test of individual network elements, such as O-RAN radio units (O-RU). Automation has always been a valuable tool for saving resources, but it is essential for comprehensive O-RAN testing due to the asynchronous hardware and software releases of O-RAN elements.
Interoperability between O-RAN elements is ensured by the O-RAN ALLIANCE, which defines the O-RAN.WG4. CONF specification. This specification is relevant for the O-RAN fronthaul open interface, and O-RUs must conform to it in addition to the 3GPP specification.
