It is an efficient alternative to transmit information, whether data, voice, video and other network services. Knowledge of the propagation process of this information in different environments is a factor of great importance for the planning and development of wireless communications systems. Because of the rapid progress and popularization of these networks, the services offered become more complex and therefore need requirements for qualities that are offered to the end user in a satisfactory manner. Because of this, it is necessary to designers of these systems, a methodology that provides a better assessment of the indoor environment. This assessment is made by analyzing the coverage area and the behavior of the metrics of multimedia services anywhere in the environment that is receiving the service. The work in this study intends to evaluate a methodology for the prediction of quality metrics experience. For this, measurements of video streaming campaigns were conducted in a wireless network and network parameters (packet/frames jitter and packet/frames loss) and some quality parameters of experience (PSNR, VQM and SSIM) were evaluated. The results showed good agreement with literature data and with measurements.porAcesso AbertoRedes sem fioQualidade de serviço (Telecomunicações)Qualidade de experiênciaModelos de propagação empíricosWireless networksEmpirical propagation modelsQuality of service (QoS)Quality of experience (QoE)DissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::TELECOMUNICACOES::TEORIA ELETROMAGNETICA, MICROONDAS, PROPAGACAO DE ONDAS, ANTENAS
