5G NR modulation and waveforms have some commonalities with LTE but aim to have much higher spectral efficiency. NR supports QPSK, 16 QAM, and 256 QAM with the same constellation mapping as LTE. An OFDM-based waveform is supported. Some parts of the numerology are flexible, like the SCS, while others are fixed. The subframe duration […]

Let’s check the main highlights if you don’t know about this big project. The main focus of this project is creating an End-to-end Open RAN compliant, UK-developed 5G SA network. It’s a complete Open RAN 5G SA network. A compact modular radio base station supporting all bands in 5G NR Frequency Range 1. The Portfolio […]

RedCap 5G NR = Reduced Capability 5G NR. As per Ericsson, It’s estimated that the number of connected IoT devices will reach nearly 39 billion by 2029, a significant increase over the number of expected smartphones at 7.7 billion. To help support the expected IoT device expansion, 3GPP introduced RedCap 5G NR, a significant addition […]

When I searched for the impact of 4G and 5G frequency spectrum on health/medical sector/hospitals, I found good Japanese research by NTT Docomo about this topic and here I concluded the main points of the study and results.  Research Area Electromagnetic interference with medical devices is caused by radio waves emitted from mobile phones and […]

📃In 2G and 3G, voice and text were the main services based on SS7 signaling. In these networks service availability was the priority. The Signal Transfer Point (STP) was the node that routed signaling messages. 📃In 4G, networks became data and media-centric and needed signaling to support smartphones and Apps. Signaling volume grew to support […]

5G needs to move from CPRI to eCPRI because eCPRI uses standards-based Ethernet for fronthaul, replacing proprietary CPRI connectivity. This shift enables higher precision timing capabilities essential for vRAN and openRAN deployments on general-purpose server hardware, making the network more flexible and cost-effective. Why 5G needs moving from CPRI to eCPRI? eCPRI enhances 5G networks […]

No doubt that Saudi Arabia is moving faster towards digital transformation including Connectivity for everyone. For that reason, you can see many trials in the NTN program. This is a summary of each trial and a simple definition for it in Airborne What is 5G NTN? 5G NTN will enable seamless roaming between terrestrial and […]

I read many papers during this year about the capabilities of microwave as a backhaul technology of 5G. I see also some claims that fiber is a mandatory technology for #5G backhauling due to the huge amount of data growth with the wider bandwidth in the spectrum in Sub-6GHz and mmWave which can exceed the 1Gpbs […]

Fixed Wireless Access (FWA), a wireless link that provides connectivity to objects that are stationary or nomadic, will receive a boost thanks to improved 5G capabilities. The first 5G use case we highlight is FWA. The demand for high-speed broadband connectivity continues to grow exponentially, driven by the increasing reliance on digital technologies and the […]

The 5GC architecture relies on a “Service-Based Architecture” (SBA) framework, where the architecture elements are defined in terms of “Network Functions” (NFs) rather than by “traditional” Network Entities. Via interfaces of a common framework, any given NF offers its services to all the other authorized NFs and/or to any “consumers” that are permitted to make […]
