ADVA last week announced that its technology has been selected for Germany’s first open radio access network (O-RAN) proof of concept (PoC).
Conducted by Telefónica Germany / O2, the field trial is a major step towards open and disaggregated RAN architectures. Built on Ensemble Activator, ADVA’s carrier-grade network operating system (NOS) running on Edgecore’s white box switches, and the OSA 5401, ADVA’s pluggable grandmaster clock and GNSS receiver, the PoC shows how Telefónica Germany / O2 can build disaggregated and vendor-neutral mobile networks that significantly reduce deployment and operational costs. The unique combination of ADVA’s expertise in carrier-grade NOS technology and its Oscilloquartz synchronization solution has enabled this PoC to go beyond other such trials and address the most stringent network timing requirements.
The multi-vendor PoC is built on ADVA’s feature-rich Ensemble Activator running on Edgecore’s switching device. Developed as part of the Telecom Infra Project (TIP), the software frees mobile network operators (MNOs) from closed proprietary systems and enables them to create vendor-neutral disaggregated infrastructure with best-of-breed components. The OSA 5401’s time synchronization capabilities are also central to the Telefónica Germany / O2 trial, including its ability to send PTP sync information and corresponding messages with precise timestamping data. The OSA 5401 also makes this advanced operation compatible with 5G radio access points from third-party suppliers and augments the accurate timing needed.

With this open RAN pilot in our O2 live network, we’re highlighting what can be achieved when industry leaders from across the value chain cooperate closely together in an open environment.

As we’re proving in multiple real-world trials with major MNOs, our Ensemble Activator is the ideal choice for turning third-party white box switches from a wide range of suppliers into disaggregated cell site gateways (DCSGs).
