Resumo-A ascensão da Internet das Coisas traz consigo um novo conceito: o LPWAN (Low Power Wide Area Network). Essas redes são caracterizadas pelo seu longo alcance, baixa taxa de transmissão e baixo consumo de energia. Este artigo visa estudar o desempenho e os limites da tecnologia LoRa, promissora para tais aplicações. Devido a uma carência de artigos que avaliem o comportamento dessa tecnologia em ambientes com características mistas, esse trabalho analisa o desempenho de um sistema de comunicação LoRa (Long Range) em um ambiente híbrido, com características tanto indoor como outdoor, localizado no campus da Universidade de Brasília. Os resultados mostram que as particularidades desse tipo de local trazem instabilidades no recebimento de pacotes e comprometem o alcance da rede, que só consegue cobrir até 86% do prédio com apenas um gateway no melhor caso.Palavras-Chave-LoRa, Ambiente híbrido, Indoor, Outdoor, RSSI, Vazão, Internet das coisas, IoT, LPWAN.Abstract-The rise of the Internet of Things comes along with an important new concept: The Low Power Wide Area Networks (LPWAN). These systems are featured with long range, low power and low bit rate. In this paper, we evaluate the limits and the performance of the LoRa (Long Range) communication, which is a promising LPWAN technology. Due to a small number of studies that discusses LoRa's performance in a hybrid environment, this paper aims to evaluate the performance of a LoRa network in an environment with outdoor and indoor properties, located at the University of Brasília. The results show that the particularities of this type of environment cause an unstable throughput and compromise coverage, reaching only 86% of the building with just one gateway, in the best case.
