| Sumario: | This thesis consists on the study of some 5G NR key features such as massive MIMO and beamforming and how they are modelled by Atoll, a network design and planning software. For this, a single cell was deployed on a sample area of Barcelona and different coverage, signal quality, capacity predictions and simulations were carried out. Some parameters such as the receiver height, the transmitter height, the number of antennas used in transmission and reception, the number of beams used by the beam-based antennas, the number of users and the different MIMO techniques, were tested and varied in order to understand their impact in area the cell can cover, its capacity, the traffic loads that can be handled and the data rates experienced by the users. From the different studies performed, it was demonstrated how beamforming improved the signal quality and the network capacity thanks the high gain beams pointed toward users. Also, it was shown how the different MIMO techniques made use of diversity and capacity gains to improve the C/(I+N) level at the receiver and the user throughput. |
