Comparative Study of Propagation Models with LTE Technology in Urban and Suburban Areas of Riobamba City

In order to determine and measure the losses in terms of wave propagation in mobile signals, propagation models are indicated to know these data, which are of great importance in the design of networks and systems, since there are several, it is necessary to determine the most effective for each environment. This article evaluates and compares various propagation models in urban and suburban environments in different areas of the city of Riobamba, thus determining the most appropriate model to implement in each area. The parameters required for each model focus especially on the heights of the base station and mobile station and also consider the coverage technology that the base station emits, generally in our country LTE signal is currently used and in few cases 3G. Finally, we compare the predictions of the evaluated models with real measurements taken in each zone with a total of 50 samples per zone, resulting in a different model for each environment.
