Resumen
Agriculture 4.0 is going to represent a massivedeployment of sensors, so efficient planning ofradiocommunication systems in this type of environment will benecessary. In this work, the measured path loss in a LoSsituation, with the transmitter and receiver heights below thetrees height, at a citrus plantation in the 1800MHz, 2100MHz,3.5GHz and 28GHz frequency bands using the FI (FloatingIntercept) and the CI (Close-In reference) models has beenanalyzed. It has been observed that from 3.5GHz, the slope ofthe FI model also represents the propagation exponent (PLE).Furthermore, a guiding effect (PLE less than 2) has beenobserved in the 1800MHz and 2100MHz bands, not in the3.5GHz and 28GHz bands, in which the PLE is practically equalto 2 (free space). Finally, the analysis of the polarization revealsthat the standard deviation of the measured values with respectto the values obtained from the models is greater for horizontalthan vertical polarization in the 1800MHz and 2100MHzfrequency bands.
