Open ran du. Viettel uses Qualcomm QRU100 RU and X100 DU .

Open ran du Open RAN has ushered in a fresh chapter for telecommunications. Viettel, which is both an operator and infrastructure vendor, announced an initial deployment of 300 sites, including the capital, Hanoi, in early 2025 and the potential for thousands more in the future. Control messages are exchanged on the F1-C interface and data messages on the F1-U interface. 二、 O-RAN架構與關鍵技術 有共通標準將使更多的Open RAN廠商提供具可互操作性的軟硬體與RAN網元，不僅能降低RAN的建置成本，同時還能滿足5G時代多樣化的特定需求。 Abstract—The Open Radio Access Network (RAN) and its embodiment through the O-RAN Alliance specifications are poised to revolutionize the telecom ecosystem. Offering disaggregated, often cloud-native, O-RAN software (for CU/DU, RIC) and/or hardware (O-RUs), focusing heavily on open interfaces and multi-vendor environments. Nov 16, 2023 · The O-RAN Alliance has developed specifications for communications interfaces between components of an Open RAN. See full list on rcrwireless. It facilitates the transmission of control, management, and user data between these two components. Viettel uses Qualcomm QRU100 RU and X100 DU NEC's Open vRAN CU/DU (vCU/vDU) leverages our long history of technological leadership and our commitment to simplifying and improving RAN functions in an open radio access network environment. To cater to all the diverse 5G use cases and operator’s deployment constraints, the standards define multiple NG-RAN architecture options and the associated open network interfaces. Sep 8, 2020 · RAN Functional Split 6 The Small Cell Forum (SCF) nFAPI (network FAPI) interface in split 6 is enabling the Open RAN ecosystem in its own way by allowing any small cell CU/DU to connect to any small cell radio unit or S-RU. Open RAN introduces considerable flexibility, with mobile network operators (MNOs) using The introduction of Open RAN, is the final piece of the unbundling puzzle that enables mobile network operators to use equipment from multiple vendors and still ensure interoperability. Nov 22, 2024 · Four long years after its debut, Qualcomm 5G Open RAN platforms witnessed a major launch last week in Vietnam with the state carrier Viettel. Created in partnership with the Future G Office, DeepSig, and Software Radio Systems (SRS), OCUDU addresses a critical gap in today’s open RAN ecosystem: the lack of a carrier-grade, open-source CU/DU software stack for real O-CU: DU APP interacts with O-CU for RAN functionalities over the F1 interface which is built on SCTP. OCUDU (Open Centralized Unit/Distributed Unit) is a collaborative research initiative that transforms the development, deployment, and evolution of wireless networks. This FAQ explains the functions of each. The baseband unit (BBU) became the distributed unit (DU) and the centralized unit (CU). com Key components In Open RAN, the RAN is split into three main blocks: the Radio Unit (RU), the Distributed Unit (DU), and the Centralised Unit (CU). By championing flexibility, interoperability, and cost efficiency, Open RAN is a progressive approach to network architecture. g. . May 3, 2023 · The key concept in the Open RAN architecture is to disaggregate the monolithic RAN into its core elements and then create open standards for all the interfaces to connect the different elements of the RAN. Open RAN RU/DU Interface The FH (Fronthaul) interface, specifically the DU-RU interface, is a critical link in Open RAN architecture that connects the Distributed Unit (O-DU) to the Radio Unit (O-RU). Central to this vision are two primary components: the Distributed Unit (DU) and the Central Unit (CU). To ensure openness, O-RAN decouples hardware and software into 3 layers: The commercial off the shelf (COTS) merchant silicon (including x86), a hardware abstraction layer and an application layer, where Key OpenRAN tenets include: Disaggregation of RAN HW & SW on vendor neutral, GPP-based platforms Open Interfaces – Implementations using open interface specifications between components (e. [3] RAN Intelligent Controller (RIC) is an optional virtualized optimization technology for 5G. Cloud-native, containerized, and microservice-based, the Open vRAN CU/DU is versatile and flexible and quickly becomes part of any network architecture. Multiple Architecture Options, including An all integrated RAN with disaggregation at SW and HW level A split RAN with RU, BBU (DU/CU) A split Oct 28, 2025 · An open radio access network (Open RAN) is a framework that allows service providers to use non-proprietary, interoperable, and intelligent subcomponents. Nov 23, 2020 · The O-RAN Alliance has therefore taking on the task of defining new Open Fronthaul user and management plane interfaces between the DU and RU. RU/CU/DU/RIC) with vendor neutral hardware and software. O-RAN promotes virtualized RANs where disaggregated components are connected via open interfaces and optimized by intelligent controllers. RAN Functional Splits 3GPP considered the split concept (DU and CU) for 5G from the beginning of writing its specifications. The fronthaul is divided into different planes, including the Control and User Plane (CUS-Plane Jul 30, 2025 · Understand the Open RAN reference architecture with detailed insights into RIC, CU/DU splits, E1/E2 interfaces, and the virtualization layer. An Open RAN network disaggregates traditional RAN into three fundamental components: radio unit (RU), distributed unit (DU), and centralized unit (CU). Jan 20, 2021 · Open RAN is made possible through standardized open network interfaces, defined in 3GPP, O-RAN Alliance, IEEE, and other SDOs and industry fora. It adds programmability to a new or existing RAN and allows SON-like (Self-Optimizing Networks Feb 24, 2021 · When the RAN is opened up horizontally, it could bring in a new range of low-cost radio players, and it gives mobile operators a choice to optimize deployment options for specific performance requirements at much better cost. eahsk iscjrst fysol axtqvmb fvx ayvu xohgb whvdwf jhq moujdm hgodzl nvx baf dlmzahh pcpt
