Posted on 348 ADVA (FSE: ADV) today 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 / O 2, 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 / O 2 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.
