| Resumo: | The Internet of Things (IoT) is becoming a reality and with it comes the need to support more devices with better coverage and low power consumption on the wireless network. One of the Low-Power Wide Wan (LPWA) technologies that aims to meet these requirements is Narrow-Band IoT (NB-IoT). NB-IoT is a 4G cellular technology particularly focused on IoT scenarios demanding for low throughput and very low energy consumption. This dissertation investigates the capacity and performance of NB-IoT technology in real-world scenarios by comparing the results of measurements performed under different radio conditions around Lisbon’s metropolitan area. Inspired by related works presented in the dissertation, the approaches adopted in this work are explained and the metrics collected are described in detail. Through practical measurements campaigns we characterize different metrics of NB-IoT performance for different propagation scenarios, identifying hypothetical causes for the observed performance. |
