How To Start Your Open RAN Career?
November 24, 2022

The Open RAN concept is based on open and standardized interfaces, which grant interoperability. Thus, it enables multiple vendors to provide different parts of hardware and software. 🧧 Although various network elements come from numerous vendors and are pro vendors to proprietary, they are designed to work together with other vendors’ products. In addition, open […]

What is the difference between Non-RT RIC and Near-RT RIC?
November 8, 2022

First, We need to know that the most important functional components introduced by O-RAN are the non-real-time (non-RT) radio intelligent controller (RIC) and the near-RT RIC. While the former is hosted by the service management and orchestration (SMO) framework of the system (e.g., integrated within ONAP), the latter may be co-located with 3GPP gNB functions, […]

Open RAN Changes Your RAN Mindset!
October 13, 2022

The RAN has been considered the most expensive part of network deployment. RAN consists of around 60-70% of the network Capex. The Open RAN (Open Radio Access Network (RAN) Journey is about changing the mindset and accepting the fact that Open RAN is not a new technology we need to test, however, it’s the future […]

How Much Cost Is Saved by RAN Virtualization?
September 28, 2022

Virtualized radio access networks (vRANs) are a way for telecommunications operators to run their baseband functions as software. One of the primary benefits of virtualizing radio access networks (RANs) is that RAN functions no longer require special proprietary hardware to run, and can instead be run on standard servers. This is achieved by applying the […]

The Complete Guide to O-RAN Alliance
September 15, 2022

What is O-RAN Alliance? O-RAN Alliance is a global alliance founded in 2018. As of June 2022, the O-RAN Alliance had 345 members and contributors (O-RAN Alliance only allows communication service providers as members, all other companies and entities are considered to be contributors). This includes communication service providers (CSP) and vendors, as well as […]

Why Physical Layer (L1) is a Big Deal in 5G Open RAN?
August 18, 2022

OpenRAN based on legacy compute architectures utilizes an excessively high number of CPU cores and energy to support 5G Layer 1 (L1) and other data-centric processing, like security, networking, and storage virtualization, and this leaves very few hosts to compute resources available for the tasks the Server was originally designed to support. Why 5G Physical […]

What is Single Root I/O Virtualization (SR-IOV)?
August 15, 2022

Single Root I/O Virtualization (SR-IOV) is a specification that allows a single Peripheral Component Interconnect Express (PCIe) physical device under a single root port to appear as multiple separate physical devices to the hypervisor or the guest operating system. It is an I/O virtualization solution supported by PCIe device hardware and developed by the standardization organization […]

What is the Accelerating Card in Open RAN World?
August 2, 2022

On the road to 4G and 5G, MNO (Mobile Network Operators (MNOs) started to think of vRAN (Virtual RAN) and Open RAN, the main difference between them you can find here.  vRAN and Open RAN architectures help for higher channel capacity and easier deployment of edge-based services and applications. vRAN and Open RAN solutions are […]

O-RAN ALLIANCE Specifications and Working Groups
July 25, 2022

The O-RAN Alliance (O-RAN) is a group that is defining specifications for radio access networks. It is a global alliance founded in 2018 and it is now comprised of close to 30 operators and more than 200 vendor companies. The O-RAN Alliance is a relatively new organization that took the 3GPP standards work as its […]

How The RIC is A Key Element in O-RAN Architecture?
July 21, 2022

In this article, I’d like to give more focus on a powerful component in the Open Radio Access Network (Open RAN) Architecture that will make an amazing shift in the RAN Automation world. Open radio access networks promise to unlock massive innovation, creating new opportunities for service providers to deliver differentiated services to consumers, businesses, […]

What is the difference between rApps and xApps?
June 30, 2022

In the Open RAN, one of the key aspects of Open RAN is going to be the fact that the intelligence in the RAN can now be supplied by a variety of vendors, as opposed to earlier generations and in the traditional RAN where all the RAN intelligence or most of the RAN intelligence was […]
