Abstract:
Among the protocols available for Internet of Things (IoT) applications, the Narrow Band-Internet of Things (NB-IoT) is one of the most relevant for presenting advantages, such as long range, low latency and low energy consumption. One of the points questioned for every protocol is the ability to serve applications that are in a mobile environment. To validate the possibility of the protocol working in this scenario, it is necessary to evaluate its performance in different propagation environments. This article presents field measurements that were made on an NB-IoT operational network in a suburban environment. The measurement results were compared with the results calculated on three propagation models used to predict loss of propagation in a mobile environment: Cost-231 Hata, ITU-1225 and Erceg Greenstein. Comparisons show that the Cost-231 Hata model offers the best performance in predicting propagation loss in the considered scenarios. These results provide relevant information about the performance of the propagation models used, applied to the NB-IoT protocol in a suburban environment
