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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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, […]

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 […]

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 […]

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 […]
