In the era of Open RAN (O-RAN), wireless network architectures are moving toward disaggregation and radio access network (RAN) virtualization, utilizing a growing number of standard interfaces. 5G design and validation teams face new and diverse test challenges to accelerate the development and integration of O-RAN-compliant equipment. Network equipment manufacturers, mobile operators and chipset providers need integrated solutions that address their evolving test requirements. These include not only traditional functional and performance test, but also conformance and compliance test against standardized interoperability specifications, such as those set by 3GPP and O-RAN organizations.
O-RAN Fronthaul Conformance Testing
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.
