E2SM RC – E2 Service Model RAN Control Procedure
Introduction In our other post Open RAN E2 Interface , we discussed that E2 is the interface between the Near RT RIC and Open RAN CU/DUs. This interface uses following […]
O-RAN Focus and Technical Work Groups Structure
O-RAN ALLIANCE is on the mission to re-shape the RAN industry towards more intelligent, open, virtualized and interoperable networks. The O-RAN standards are working to enable a more competitive and […]
Open RAN Integration – Where We Today
Open RAN is being deployed by multiple Service Providers around the world. These deployment are large scale deployments in some of the largest countries in the world. In Open RAN […]
O-RAN Distributed Unit (O-DU) Reference Architecture
The O-RAN or Open Distributed Unit (O-DU) is a commercial off-the-shelf (COTS) edge servers that can function as baseband processing unit to handles high PHY layer, MAC and RLC layer […]
O-RAN – Radio Unit (O-RU) Reference Architecture
The Radio Unit (RU) purpose is to convert radio signals sent to and from the antenna to a digital signal that can be transmitted over the fronthaul to Distributed Unit […]
O-RAN – Fronthaul Delay and Its Management
O-RAN Split Option 7-2x, introduced a functional split between O-DU and O-RU within the PHY Layer of the radio interface. This split cause some delay in transmission and reception of […]
O-RAN Fronthual C-U/Sync/Mgmt Planes and Protocol Stack
The interface between DU and RU is known as Fronthaul. When this interface allows to connect any vendor DU to any vendor RU, know as Open Fronthaul. To enable this multi […]
O-RAN Fronthaul Transport Synchronization Configurations
O-RAN maintains network timing distribution as the preferred approach within the fronthaul network. Time and frequency synchronization needs to be distributed to O-DU and O-RU for the effective O-RAN network […]
Open RAN (O-RAN) Reference Architecture
O-RAN Tutorial The O-RAN Reference Architecture is designed to enable next generation RAN infrastructures. It is designed with the principles of intelligence and openness, the O-RAN architecture is the foundation […]
