Before talking about the challenges of 5G Network planning and optimization in the mmWave band, let’s start with the common question, Why we need mmWave especially for 5G technology? History of High Frequencies in Mobile Communication While high frequencies have been used for point-to-point network backhaul links, cellular carriers have never before made common use […]

The mobile industry is currently discussing Virtualized RAN (vRAN) and Open RAN, but it is vital to distinguish between these two concepts because they represent different approaches. These two initiatives serve different purposes that may often overlap. From a high-level perspective, the two initiatives are described below • vRAN These networks decouple software from hardware […]

One of the big challenges nowadays in 5G technology is the Uplink or UL. Historically, most mobile network traffic has been on the downlink since users have long craved high data speeds to download their favorite videos. With the new normal, and the increase in video conferencing, the uplink traffic increase by up to 40 percent, putting a significant strain on the uplink as per […]

All 5G iPhone 12 models support Dual SIM mode, which refers to the ability to switch between a SIM card and an eSIM operating on independent numbers and/or carriers. However, an image of a training document from Apple’s Sales Web resources called “What you need to know about 5G on iPhone” and posted to Reddit suggests the ‌iPhone 12‌ will […]

Finally, Apple Inc on October 13,202 launched its next-generation iPhone 12, with faster 5G connectivity. The company announced four new iPhones in a virtual event on Tuesday — the iPhone 12, the iPhone 12 Pro, the iPhone 12 Pro Max, and a new, smaller, iPhone 12 mini. All the phones are 5G-equipped, meaning they can […]

T-Mobile and Ericsson teamed up on a 16-layer multi-user multi-input multi-output (MU-MIMO) demonstration, showcasing peak cell throughput of more than 5.6 Gbps! That’s on one channel of the 2.5 GHz spectrum. During the test, engineers connected 8 separate smartphones to the same 5G radio and resources and, thanks to MU-MIMO — a fancy term for […]

One of the most common questions I face every day What is Beamforming? How Beams are formed?, Actually I read some interesting topics from latest Huawei white paper about 8T8R Antenna Beamforming. let’s see the answer.  What are the Principles of 8T8R Beamforming? Beamforming is a digital signal processing technology that can be implemented on […]

Introduction Simply put, virtualization is an idea whose time has come. The term virtualization broadly describes the separation of a resource or request for a service from the underlying physical delivery of that service. With virtual memory, for example, computer software gains access to more memory than is physically installed, via the background swapping of […]

NFV Architectural Framework The architecture that defines traditional network devices is fairly basic because both the hardware and software are customized and tightly integrated. In contrast, NFV allows software developed by the vendors to run on generic shared hardware, creating multiple touch points for management. The NFV architectural framework is developed to ensure that these […]

Option 3 Introduction The initial deployments of 5G services are based on 5G NSA, also called option-3. The variants of option-3 are option-3, option-3a and option-3x. Option-3/3a/3x is transparent to MME and P-GW and translates to an E-RAB modification procedure at MME. Option-3: Traffic is split across 4G and 5G at eNodeB. Option-3a: Traffic is […]

New Lab Demonstration Uses MU-MIMO Technology to Showcase 5G’s Vast Capacity Samsung’s 5G New Radio (NR) Access Unit (AU) supporting 28GHz spectrum. Using two test mobile devices, the demonstration achieved approximately 4.3Gbps speeds on each, reaching an industry peak speed of 8.5Gbps across both devices. In order to achieve the speed, two key technologies were used: carrier aggregation CA and […]
