What is The Difference Between vRAN and Open RAN?
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

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 […]
When should MNOs shut down their 2G and 3G Networks?
Many of my friends asked me why MNOs (Mobile Network Operators) didn’t switch-off legacy networks like 2G and 3G till now. Yes, this is a good question specially day-by-day I […]
What is the Accelerating Card in Open RAN World?
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 […]
