Abstract:


In this article a study has been conducted of propagation loss in outdoor environments. This involved carrying out a measurement campaign in several streets and avenues of the city of Belém (Pará State), both in the central area where there is a good deal of construction of high-rise buildings and on the outskirts where the buildings are lower. Some models from the literature were used to compare the predicted propagation path loss values with the values obtained during the measurement campaign. It was found that with these particular measurements, the models for propagation loss did not have curves that were similar to the measurements found in the routes and had a high prediction error. In view of this, all the prediction models were optimized on the basis of a Genetic Algorithm (GA). Through this technique, there was a better outcome in the models that were studied than with the losses found in the routes that were covered.
