Pre-5G Satellite Systems 5G-based Non-Terrestrial Networks (NTNs) are expected to become increasingly common in the coming years. At the same time

In a Non-Terrestrial Network (NTN), different types of beams can be used to provide radio coverage over the Earth's surface. According to the 3GPP approach

As discussed in Chapter 1, the Uncrewed Aircraft Systems (UASs) considered in this book as part of the Non-Terrestrial Networks (NTN)

Non-Terrestrial Networks (NTNs) provide significant flexibility to network operators by supporting different types of non-terrestrial platforms.
