The RAN has been considered the most expensive part of network deployment. RAN consists of around 60-70% of the network Capex. The Open RAN (Open Radio Access Network (RAN) Journey […]
Open RAN Changes Your RAN Mindset!
How Much Cost Is Saved by RAN Virtualization?
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 […]
5G is Not Hazardous To Your Health
All generations of mobile phone technology, including 5G, take the same familiar underlying approach. A mobile network consists of a nationwide grid of cell sites. These sites feature transmitters that […]
3GPP Architecture for 5G NR
As per 3GPP, The gNB is divided into two logical functions: the CU and DU. The DU is the baseband unit in a 5G RAN. It handles layer 1 and […]
5G 3GPP Releases from Release 15 to Release 18
5G is an evolving standard. The initial version of 5G was accomplished with the freezing of Release 15 late-drop in summer 2019. Enhanced features originally were introduced in Release 15 […]

IMS Is The Core of VoLTE Network
Voice over LTE, or VoLTE is a GSMA profile of the standards defined for the delivery of services currently provided via Circuit Switch networks – mainly voice and SMS – […]
Why Is 5G Growth Faster Than The Previous Generations?
5G can be significantly faster than 4G, delivering up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-second (Mbps) average data rates. 5G has more capacity than 4G. 5G is […]
3GPP Yang Model for nrCellDU “5G SW Development”
3GPP TS 28.541 explains how Yang models are implemented in 5G gNB in gNB-CU and gNB-DU as below: The nrCellDU table models a geographical area of radio coverage that is implemented […]
Why Physical Layer (L1) is a Big Deal in 5G Open RAN?
OpenRAN based on legacy compute architectures utilizes an excessively high number of CPU cores and energy to support 5G Layer 1 (L1) and other data-centric processing, like security, networking, and […]
What is Single Root I/O Virtualization (SR-IOV)?
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 […]
