What is O-RAN and its Characteristics O-RAN Concept O-RAN Architecture O RAN (Open RAN) refers to industry-wide standards for RAN (Radio Access Network) interfaces; it supports interoperation between vendors’ equipment. As a result, the technology offers network flexibility at a lower cost. :::info It is a disaggregated approach to deploying mobile fronthaul and midhaul networks built entirely on cloud native principles. ::: O-RAN technology decomposed the existing Baseband Unit (BBU) into two functional components, a Distributed Unit (DU) and Central Unit (CU). Conforming to modern control user plane separation (CUPS) constructs, the Central Unit can be further decoupled into distinct control plane (CU-CP) and user plane (CU-UP) functions, replacing the monolithic BBU with the CU/DU allows for new deployment models.
