RAN Virtualization in 5G Network
December 7, 2019

What is Virtualization? Virtualization means decoupling software from hardware, enabling mobile network operators to handle dynamic and challenging use cases, such as enhanced mobile broadband (eMBB), massive connectivity (mIoT), and ultra-reliable and low latency communications (URLLC). It allows you to use a physical machine’s full capacity by distributing its capabilities among many users or environments. […]

EPC Core Upgrade for 5G EN-DC
November 1, 2019

  At first, we need to identify the meaning of word EN–DC, It’s E-UTRAN New Radio Dual Connectivity. Simply it means the possibility of UE to get simultaneous data from LTE eNB and 5G gNB.  In EN-DC, the radio access network is composed of eNBs (eNodeBs) as the master node and gNBs (gNodeBs) as the […]

Dual Connectivity From the 1st Session of 5G RAN Training: How does Dual Connectivity improve the total BW. Also the limitation of using FDD for LTE and TDD for 5G NR. The Subcarrier Spacing plays an important role in expanding the total BW but it also has a limitation in the case of EN-DC. Did you […]

10 Learned Lessons from 5G Asia!
September 11, 2019

I summarized these #10 5G Learned Lessons from #5G_Asia and RCRWireless report about this big event  1- Operators should focus on replacing their legacy networks to pave the way to all IP networks, with new IT infrastructure rather than telco components.  2- A standalone 5G network requires a much more IT-centric approach to can support different use cases […]

15 kHz as 5G Baseline Numerology 5G RRC States In 5G and the previous generations, the device can be in different states depending on the traffic activity. NR device can be in one of three RRC states, RRC_IDLE, RRC_ACTIVE, and RRC_INACTIVE. The first two RRC states, RRC_IDLE and RRC_CONNECTED, are similar to the counterparts in […]

5G Stand Alone (SA) Beam Management
July 5, 2019

In this article, I will explain the Beamforming technique in 5G to compensate for path loss especially in the mmWave spectrum range. As the range of mmWaves is between 30 GHz and 300 GHz, a wavelength is between 1 millimeter and 10 millimeters and this is the intensive motive for Beamforming. Beamforming Definition The beamforming […]

What Is Voice over New Radio (VoNR)?
June 21, 2019

As the VoLTE adoption cycle, it took the industry a few years to plan, test, and commercialize new voice services, and I believe VoNR will follow a similar timeline. And since 4G is the foundation for 5G NR deployments, I expect VoLTE to remain the 5G voice solution for many years to come. 5G NSA […]

What Is the Difference between Static and Dynamic TDD?
May 24, 2019

Duplexing is one of the most important factors that impact the performance of 5G networks in terms of its wide-area coverage. 5G NR gives support to multiple duplex modes, that includes static TDD, FDD, and flexible duplexing. It is expected that 3.5GHz TDD is the first spectrum for early 5G deployments. Static TDD, the UL/DL […]

Everything You Need To Know about Beamforming
May 10, 2019

In this article, I’ll start with its motivation. Then I’ll answer the question: What is Beamforming? And also discuss its types, especially Hybrid Beamforming. Beamforming Motivation: The 5G main goals are to achieve higher data rates, lower latency network accesses, and support and fix different use cases. With higher data rates, the need for wider […]
