A study of signal penetration into building materials

This paper reports on the measurements performed for different building materials, different building thickness, different openings and combination of two or all of the variables, that have significant impacts into signal penetration in buildings through experiment setups. Signal strength is measured within the frequency range of 800MHz to 3GHz in the anechoic chamber to determine the signal strength loss due to building materials used. This paper also emphasizes on the design of the anechoic chamber and its absorber in aspects of dimension and type of material used.
