| Sumario: | Narrow band Internet of Things (NB-IoT) is a technology that has been growing in recent years and will continue to play an important role in fifth (5G) and sixth (6G) generations of mobile communications in upcoming years. NB-IoT covers a big part of the communication market segment with several examples including monitoring of smart cities, agriculture, cattle and forest or a variety of industrial applications. Some of these scenarios are remote places where there is not an accessible terrestrial network and there is also not a great demand of service to deploy a new one. One solution to address this issue is the use of Non-Terrestrial Networks (NTN) which would guarantee satellite connectivity to these remote areas. On this project, a MATLAB code has been developed to simulate a satellite scenario where several NB-IoT devices will try to access the satellite using a Random Access (RA) procedure. With the help of the simulations, it has been determined which parameters of the RA are the most critical to the system capacity. Four methods are proposed which can help to equalize the capacity across the NTN cell to guarantee fairness for all User Equipment (UEs). |
