Comparison of Propagation Models Using Propagation Features

Resumo

The propagation model is a critical point for predicting the coverage area. The complexity of the coverage prediction is enhanced by the possibility of SFN (Single Frequency Network) operation, which allows the installation of auxiliary relays in shadow areas. By knowing the techniques used by each propagation model, it was possible to use the literature as a reference to categorize the types of paths by the propagation situation. This paper presents a comparison study of the simulated propagation models in the Progira software with field measurements in a massive SFN of RecordTV Rio, in the city of Rio de Janeiro. The comparison considered the error mean in all the paths and each of types of paths, so it was possible to obtain an overview of which propagation model is best suited for each propagation situation. It presents details of the techniques used in propagation models, a brief review of the main propagation models and the mean of errors for each type of paths. The results presented contribute to a better interpretation of which propagation model or the propagation model technique can be more efficient in a micro-region, which can optimize the planning of an auxiliary transmission.
