O-RAN Fronthaul 7-2x in One Page
September 7, 2021

In Split 7.2x: Low PHY/High PHY split, The Low PHY/High PHY split is the most acceptable approach for it is less complex and it supports various fronthaul requirements and most importantly it has high virtualization benefits. Split 7.2x is the O-RAN Alliance fronthaul specification between O-DU to O-RU. It has two variants: 7.2a and 7.2b based […]

RAN Intelligent Controller (RIC) Use Cases
August 29, 2021

O-RAN Alliance has committed to evolving Radio Access Networks (RAN) around the world. Future RANs will be built on a foundation of virtualized network elements, white-box hardware, and standardized interfaces that fully embrace O-RAN’s core principles of intelligence and openness. An ecosystem of innovative new products is already emerging that will form the underpinnings of […]

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 […]

Open Interfaces by O-RAN Alliance
July 30, 2021

The O-RAN ALLIANCE e.V. specifies profiles for 3GPP RAN interfaces to achieve interoperability among different vendors. So far, profiles for open X2, open Xn, and open F1 interfaces have been published. Open X2 enables operators providing 5G Non-StandAlone to introduce 5G NR base stations (gNBs) independently of the vendor providing 4G LTE base stations (eNBs). Open Xn […]

What Is The Importance of RIC?
July 5, 2021

O-RAN Alliance came up with RAN Intelligent Controller (RIC) to enable AI/ML-based RRM optimization, and which is expected to be merged with the existing central Self-Organizing Network (SON) function. Traditional RAN can’t achieve the next-generation RAN activities from operational efficiency, automation of configuration and optimization activities, and customer level-specific service assurance. As next-gen RAN will […]
