vRAN is a new architecture enhancing the flexibility of Centralized RAN (C-RAN) by virtualizing the functions of basebands in a common resource pool made up of the Commercial Off-the-Shelf (COTS) servers located in a centralized Hub, allocating resources in a flexible manner according to traffic conditions. vRAN = Virtual Radio Access Network Why vRAN? Maintaining […]

There are several industry-led open RAN initiatives that seek to unite an ecosystem of supply chain partners and advance open RAN through the definition, development, and testing of standards and reference architectures. Beyond the standards defined by the 3rd Generation Partnership Project (3GPP), multiple industry groups are leading the open RAN movement, each with a […]

There are different acronyms related to the evolution of RAN (Radio Access Network), like vRAN, open RAN, O-RAN, etc.  A key point to clarify is that RAN evolution means both the disaggregation of mobile network base stations into more standardized entities (this is widely known as functional split), as well as the introduction of cloud […]

Open RAN is a highly disruptive technology that will bring many benefits to Mobile Network Operators (MNOs), especially during the evolution to 5G. By opening up the RAN to multiple vendors and virtualizing the software, costs will be significantly reduced, highly dynamic services will be enabled, and the RAN domain will experience far greater levels […]

If we’re talking about RAN Market Status, The mobile RAN equipment market (covering active base station equipment and antennas, but excluding power supplies, cable, install costs, civils, passive antennas, etc.) was worth about $33 billion in 2019, according to Omdia, and is forecast to grow to $36 billion in 2023.  So the R&D in different […]

Open and virtualized RAN, Open vRAN refers to a disaggregated approach of deploying virtualized mobile networks by using open and interoperable protocols and interfaces, implemented over a common propose hardware in a multi-vendor software environment, allowing increased flexibility over traditional RAN architectures., aiming to provide OPEX and CAPEX savings while fostering innovation. Traditional RAN Protocol […]

Industry Alliances and Organizations Multiple industry groups are working on 5G deployments and standards. These groups include: O-RAN Alliance: A group of telecom companies focused on fostering wireless networks that are open software-defined and virtualized, enabling architects to mix and match products from different In 2018, the xRAN and C-RAN organizations merged to form O-RAN. […]

Functional Split Options for 5G Networks As network architects work to meet the 5G challenges of increased traffic and data flows, a fundamental question is how much intelligence to put near the antenna versus at the DUs or CUs. Mobile Network Operators (MNOs) as well as industry-standards groups, such as the 3GPP, IEEE, Telecom Infra […]

The main motive for the RAN Intelligent Controller (RIC) is to bring software-defined controllability to RAN to increase system performance as on the path towards 5G, with network densification, and availability of different types of spectrum bands, it is increasingly a more difficult task to optimally allocate radio resources, implement handovers, manage interference, balance load […]

In the cellular network, RAN provides wide-area wireless connectivity to mobile devices. Towards this end, it conducts two fundamental tasks: It converts IP packets to Physical Layer packets suitable for transmission over the time-varying mobile channel using packet and signal processing techniques. It conducts Radio Resource Management (RRM) control to determine how best to use […]

The “Cherry” Release of O-RAN Open Software  • Cherry features significant advancements in the end-to-end integration of O-RAN Architecture components. • The software now contains new functions aligned with the latest O-RAN specifications, such as the E2, A1 or O1 interfaces. In December 2020, the O-RAN Software Community (OSC), working with the Linux Foundation, published […]
