SMS stands for Short Message Service and is used both for end-user messages and between the network and the device without any human interaction. There are two options for SMS when the mobile is attached to a 5G network without the need to fallback to a 4G network: • SMS over IP. • SMS over NAS […]

5G standalone (SA) operation, using a new core network, is foundational to mobile operators seeking to offer advanced 5G services with a low cost of production. 5G Service-based architecture (SBA) In a SBA framework, the individual elements are defined as Network Functions (NFs) instead of Network entities. Through Service Based Interface (SBI) each of the […]

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 […]

First, we need to understand the definition of Fronthaul. Fronthaul is the transmission connection between the Radio Frequency (RF) module and the baseband processing Unit (BBU) in the mobile wireless network.  In the traditional distributed RAN or D-RAN, the fronthaul distance is short as the RF module and BBU are directly connected via optical fibers. […]

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 […]

If you look at how security was addressed in the 4G core (EPC), you had perimeter devices, whether it’s firewalls, security devices that protect from denial of service attacks, or just security gateways at the periphery, and you had fewer vendors addressing the core infrastructure. So, if you have a single core vendor, the risk […]

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 […]
