propagação, rádio enlace, estatístico, software, modeloResumo
O processo de investigação está baseado no desenho de um aplicativo desktop para provas de cobertura em interiores e exteriores de enlaces sem fio na banda de frequências de 2,4 GHz com o uso de software livre, que permite capturar, processar, analisar, calcular e gerar um modelo matemático de tipo estatístico em tempo real do hardware do controle de acesso à mídia (MAC) incorporado na placa de rede sem fio de um computador portátil – laptop- que detecta o nível de potência, as portadoras e outras variáveis dentro dos tramas de informação que transmitem as estações base. A metodologia é experimental. Primeiro, são analisados diferentes modelos de propagação, depois, são estudadas as ferramentas de prova existentes e depois se comparam as tecnologias e ferramentas de hardware e software; se seleciona a linguagem de programação e finalmente gera-se o código e a interfase gráfica do aplicativo com a finalidade de visualizar o modelo matemático expressado por meio do uso de mínimos quadrados com o algoritmo de Levenberg-Marquardt e compará-lo com modelos de propagação reconhecidos.
