What is the difference between rApps and xApps?
June 18, 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 […]

How Much Cost Is Saved by RAN Virtualization?
May 16, 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 […]

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 […]

What are C/U/M/S Fronthaul (FH) Planes in ORAN ?
May 5, 2022

O-RAN’s proposed concepts and architectures use a split-RAN concept. There are 8 known ways to functionally split the RAN, and each one proposes splitting the processing so that different parts of the protocol stack process on different hardware. The below Figure summarizes the eight options. O-RAN has specified a version of the 7-2 split. The […]

Open RAN Interoperability Between Multi-Vendor!
April 17, 2022

For the introduction of RAN functions disaggregation and open interfaces in 5G, 3GPP has in Release 15 specified a Higher Layer Split (HLS) option of the gNB, which is also known as the Option 2 NR-PDCP split option. In this option, the gNB may consist of a Central Unit (gNB-CU) and one or more gNB […]

Why Do We Need to Change the RAN Mindset?
April 6, 2022

First, We need to understand the most important question, Why do we need to change our RAN from a traditional setup to a more flexible one? The Answer is: Heavy Data Growth Each new mobile technology generation has delivered greater data rates to mobile devices, and mobile users have moved more and more of their […]

Why 7.2x split is the Best Split Option?
March 13, 2022

O-RAN’s proposed concepts and architectures use a split-RAN concept. There are eight known ways to functionally split the RAN, and each one proposes splitting the processing so that different parts of the protocol stack process on different hardware. The below figure summarizes the eight options: O-RAN proposes using option 7-2 which splits the physical layer […]

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 […]
