Description:
Welcome to our course on 5G Non-Terrestrial Networks (NTN), where we explore the groundbreaking integration of satellite technology into 5G architecture. As global demand for reliable and fast connectivity grows, NTN is revolutionizing how we think about communication networks by extending coverage to even the most remote areas on Earth. This course offers a comprehensive dive into the key components, use cases, and architecture of 5G NTN, with detailed insights into satellite orbit types, the role of leading satellite providers, and the latest standardization efforts. Whether you are a telecommunications professional, a tech enthusiast, or a student in communications technology, this course will equip you with the knowledge to harness the potential of NTN in 5G networks.Course Contents:Section 1: Introduction to Non-Terrestrial Networks (NTN)5G NTN Use CasesSatellite Orbit Types: 1.
