Transmission and isolation of signals in buildings at 60 GHz

This article presents a model, based on reflection and transmission of plane waves in a dielectric slab, for the estimation of transmission and isolation through building walls and floors at 60 GHz. The internal reflections is negligible for the usual thickness of building materials, with the exception of glass, acrylic glass and plasterboard. In the same conditions, the estimation of the isolation can be done by using the product of the attenuation coefficient and the wall thickness, and it is seen that at least a value of 20 dB is obtained. As a general conclusion, only glass and plasterboard are not effective in isolating cells with the same frequency group
