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 […]

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 […]

5G MENA is one of the largest talked-about events in the MENA region that focuses on advancing and commercializing 5G networks. This year it was held in Jumeirah Beach Hotel, Dubai, from 7 to 9 April 2019. It was my first time to attend this event and it was very interesting and informative experience.  This […]
