Service providers worldwide are driving adoption of an open radio access network (RAN). The O-RAN Alliance has defined a 5G RAN architecture that breaks down what was once a single-vendor, hardware-centric RAN into several sections with standardized interfaces between them.
Making open RAN work calls for stringent testing requirements. With the introduction of the open RAN and a distributed RAN, it is now necessary to test each component in isolation for conformance to the standards. It is also important to test the components in combinations for interoperability.
