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 […]

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, […]

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 […]

The Road to Open RAN
December 3, 2021

The Road to Open RAN is not easy one, there are a series of steps should be taken before migration or starting design the network architecture based on Open RAN. Either you’re a green field needs to start a new network from scratch or even a brown field and re-think of the open RAN concept, […]

Evolving RAN Architecture to Open RAN
October 27, 2021

Open RAN has gained prominence in the last few years due to ongoing trends towards openness and disaggregation in the mobile network operator (MNO) space and spurred by recent geopolitical pressures. The below explanation is part of Unlocking Open RAN — An Infrastructure Viewpoint white paper. Evolving RAN Architecture to Open RAN Over the different […]

Open RAN Technical Priorities by 5 European Operators under MoU
October 26, 2021

On January 2021, Five big European operators, Deutsche Telekom AG, Orange, Telefónica, Vodafone Group and TIM (which joined in Feb 2021) are signed Memorandum of Understanding (MoU) to provide a framework for a specific commitment to support the development of a non-fragmented global OPEN RAN ecosystem for deployment across the European network footprint of each […]

9 Reasons for OPEN RAN deployment
October 20, 2021

The Open RAN concept is about building networks using equipment that separates the vendor-specific software and vendor-specific hardware associated with the vast majority of radio access network (RAN) equipment that is available today from a handful of cellular equipment vendors. Open RAN, then, uses RAN software on commercial, off-the-shelf hardware (COTS). There are 9 main […]

What is the difference between vRAN and Open RAN?
September 28, 2021

It is important to distinguish between vRAN and Open RAN Virtualization is a journey that the telecoms industry has been on for several years to transform network functions into virtual network functions (VNFs). The VNF software is then decoupled from the purpose-built hardware and run on standardized, common off-the-shelf (COTS) hardware. The interfaces between each […]

What is vRAN?
September 5, 2021

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?
