Abstract

The main objective of this thesis is the study and analysis of the inclusion of non-terrestrial components in 5G networks, namely satellites. To achieve this goal, fundamental concepts of the 5G system have been introduced, focusing specifically on developing and analysing models of coverage, capacity, and latency. Through the model and various simulations, several satellite architectures and scenarios are explored, evaluating the impact on key performance indicators for different cases. The results obtained show the importance of parameter exchange for coverage extension, the influence on capacity increase, and the impact on latency, providing valuable insights into the implementation of this network. This model serves as a tool for network optimisation and resource allocation, as well as identifying limitations. Regarding LEO satellites, a percentage of 2% of served users is achieved for the most demanding service. This thesis demonstrates the potential of satellite networks for extending 5G coverage to rural or underserved areas, along with the associated challenges.
