O século XXI experimentou uma explosão de dispositivos conectados à internet, chamada de a era da Internet das Coisas (internet of things - IoT). As redes sem fio desempenham um papel fundamental na interconexão dos dispositivos IoT, tanto sensores quanto atuadores. O objetivo deste trabalho é investigar a propagação de sinais de dispositivos sem fio nas frequências de 900 MHz e 2450 MHz, utilizando dispositivos IEEE 802.15.4 e LoRa.
