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? Maintaining […]

O-RAN Alliance, TIP, ONF and Open RAN Policy Coalition
August 27, 2021

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 […]

vRAN Shouldn’t be Equal to Open RAN nor ORAN
August 20, 2021

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 […]

Why Do We Need a New OSS/Orchestration in Open RAN?
August 8, 2021

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 […]
