Really I am writing this article due to two reasons, First that I received many questions about Is 5G Safe for Human? and Second that I shocked when I saw some of the social media posts on Facebook and Twitter that point out that the main reason for COVID-19 is 5G or using some 5G […]

Release 16 is designed to be an 18-month project that wraps up at the end of 2019. The three key performance indicators for 5G are faster peak rates (the enhanced mobile broadband, eMBB), more connections per cell (massive machine-type communication, mMTC), and lower latency (ultra-reliable low-latency communications, URLLC). Most of Release 15 focused on the […]

As per the Ericsson Mobility Report, November 2019, by the end of 2025, we expect 5G to have 2.6 billion subscriptions covering up to 65 percent of the world’s population and generating 45 percent of the world’s total mobile data traffic, making it the fastest developing mobile communication technology to have ever been rolled out […]

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. […]

  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 […]

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 […]

VoLTE is the all-IP method that tightly links the voice application to the LTE network to assure the best subscriber experience in terms of performance, reliability, interoperability and global roaming. The Value of VoLTE It integrates voice with 4G LTE to ensure the critical reliability and quality of that voice service. It ensures subscribers continue […]

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 […]

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 […]

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 […]

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 […]

Through my research I found this nice story that illustrates the three main use cases for 5G:  To understand the three broad use cases that 5G wireless technology seeks to transform, consider a typical morning office commute in a 5G-connected car just a few years down the road. The vehicle is continuously changing position, behavior, […]

5G Core Network  End-to-end flexibility is confirmed to be one of the core features of future 5G networks. This flexibility will result in large part from the introduction of network softwarization, i.e., the network hardware and the software functions are separate. Network softwarization through network functional virtualization (NFV), software-defined networking (SDN), network slicing and Cloud-RAN […]

Introduction 5G will give a diverse and new set of services and use cases affecting nearly every aspect of our lives. But to exceed all expectations, 5G-enabled services and applications must be delivered securely. For example, 5G will support Massive Internet of Things (MIoT) implementations like traffic sensors and Vehicle-to-Infrastructure (V2I) services that are the […]

Introduction  The December 2017 deadline for the primary set of New Radio (NR) technical specifications, known as early drop out/December acceleration, was finally achieved. – This acceleration was originally motivated to be updated with proprietary fixed wireless access solutions in mmW. – The early drop out scope is limited to Non Stand Alone (NSA) NR, […]
