A técnica de Domínio de Tempo de Diferença Finita (FDTD) é apresentada neste artigo como um método de estimativa para previsão de propagação de rádio em ambientes de rede local sem fio (WLAN) grandes e complexos. Sua validade é demonstrada pela comparação das medidas e do método Ray-trace com os dados do FDTD. As bandas de frequência de 2 GHz (802.11b/g) e 5 GHz (802.11a) são usadas tanto nos cálculos quanto nos experimentos. A distribuição de força do campo elétrico (campo E) foi ilustrada na forma de histogramas e gráficos de razão cumulativa. Ao utilizar o método FDTD para variar o número de corpos humanos no ambiente, os efeitos na distribuição do campo E devido à absorção do corpo humano também são observados para o projeto WLAN de 5 GHz.

Abstract: The Finite-Difference Time-Domain (FDTD) technique is presented in this paper as an estimation method for radio propagation prediction in large and complex wireless local area network (WLAN) environments. Its validity is shown by comparing measurements and Ray-trace method with FDTD data. The 2 GHz (802.11b/g) and 5 GHz (802.11a) frequency bands are used in both the calculations and experiments. The electric field (E-field) strength distribution has been illustrated in the form of histograms and cumulative ratio graphs. By using the FDTD method to vary the number of human bodies in the environment, the effects on E-field distribution due to human body absorption are also observed for 5 GHz WLAN design.
