Wave Propagation into Buildings

Abstract

This paper investigates radio wave propagation into buildings illuminated from an out- door base station with an antenna above the rooftop. Field strength measurements are taken in four buildings in urban microcells. Results of our experiments as well as those of several other authors are analyzed and the important factors influencing building penetration loss have been discussed namely angle of incidence, external wall configuration, receiver height and significance of non-line-of-sight surface of the building.
