High wireless communication systems demands in a variety of office, public and residential environments requires the electromagnetic properties of building materials to predict the indoor wave propagation. This paper describes the equivalent electrical properties of typical building walls composed of several building materials. We estimate the complex specific dielectric constant of building materials composition from the spatial transmission loss measurements and discuss the dispersion of the measured transmission loss. The validity of the estimated equivalent dielectric constant is discussed by a comparison of the reflection loss between the measurement and the prediction. This spatial reflection loss measurement can be one of the effective methods to determine the equivalent electromagnetic properties of composite building walls.
