The study of propagation loss in the Amazon region cities involves an environment characterized by tropical climate and suburban environments densely arborous. Based in the importance of ISM band 5.8 GHz, this work presents a propagation model for this frequency band, combining the characteristics of attenuation experienced by a radio wave when it propagates in typical environments found in Amazon region cities. For such purpose, measurements of the received power were carried out in 335 fixed customers distributed in 12 towns in northern Brazil, which are served by digital inclusion program in the state of Pará, Navega Pará. Measurements with mobility were also carried out on the Federal University of Pará (UFPA) area. Still, it is present...
