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 […]

What the Open RAN Main Components?
June 3, 2022

Open RAN disaggregates the RAN into main 3 components as below: 🧧 Upper Layer Split Central Unit (CU) • Logical node that includes a portion of the eNB/gNB functions as defined by split option 2 (PDCP RLC). • CU can support many O-DUs. 🧧 Lower Layer Split Distributed Unit (DU) • Logical node that includes a […]

Why RAN Must Be OPEN?
May 25, 2022

RAN (Radio Access Network) is the main telecommunication network component that is located between the core network and users’ equipment (such as a mobile phone). RAN is constituted of a Radio Unit (RU), which is the antenna visible on top of a cell tower, and a Baseband Unit (BBU), a set of devices linking the […]

Everything You Have To Know About PTP or Precision Time Protocol?
May 13, 2022

Introduction Several time synchronization mechanisms can be used in a network. The most common standards are Network Time Protocol (NTP) and Precision Time Protocol (PTP). NTP, which is the older, well-known protocol, is currently in its fourth version. NTP was primarily developed to achieve accuracy in the submillisecond range and is widely implemented for network […]
