A Non-Terrestrial Network (NTN) is a wireless communication system that utilizes space-borne or airborne platforms—such as satellites, high-altitude platforms (HAPs), or drones—to directly provide connectivity to devices on the ground. Within 3GPP, the term NTN generally refers to satellite and HAP-based systems. The motivation for NTN is simple yet powerful: extending wireless coverage beyond the…

For years, the telecom industry has been waiting for 5G Standalone (5G SA) to deliver on its promise. Progress has been steady rather than spectacular, and subscriber numbers remain modest compared to the early hype. Yet, recent figures show that 5G SA is now emerging as a major growth engine for the mobile core network…

The rollout of 5G technology is reshaping how we connect, making communication faster and more reliable than ever before. At the heart of this revolution is MIMO (Multiple Input Multiple Output). This technology is and remains a game changer, significantly boosting data speeds, enhancing capacity, and improving the overall reliability of networks. This article will…

Beamforming is an effective technique that enables precise directional coverage while significantly minimizing interference and noise from other directions. Beamforming and MIMO are crucial aspects of modern communication systems in 5G, where significant challenges like increased path loss and throughput are demanded. Massive MIMO and beamforming techniques are extensively used to enhance coverage, capacity, and…

In our previous post, we covered the cell search and downlink synchronization procedures. Today, we will discuss the RACH in 5G part, if you missed our first post, please refer to it for background information. Figure 1 1. prach_ConfigurationIndex: This parameter will refer to the table defined by 138.211. indicating the PRACH format to use,…

5G networks offer higher download speeds and lower latency than older 4G networks, while most actual 5G connections are supported by 5G non-standalone (NSA). Wireless operators are increasingly deploying 5G standalone (SA) technology, as 5G SA will drive new use cases and unlock the advanced capabilities of 5G so In this article, which is the…
