Validating a Channel Model Propagation in Outdoors Scenarios by Using Bootstrap Method

This article presents the validation of a semi-empirical channel model propagation for outdoors scenarios in the frequency band of 2.4 GHz, with ZigBee technology by using bootstrap method. This model is estimated from the indicator of the strength of the signal received based on data captured in rural and suburban scenarios, in a range from 2 to 200 meters. Contrary to several articles of literature, we detected a discontinuity at 60 meters, we used linear regression to obtain the main features of channel model and validate the model with bootstrap technique. The results identify the main parameters of the model and we determine a correction factor in order to obtain a unique expression in both sections.
