Radio Wave Propagation

This thesis deals with Radio Wave Propagation in environments where the propagation is severely influenced by surrounding objects, mainly walls and other building structures. As an introduction, a brief description is given on propagation terms like loss, delay and dispersion along with system functions relevant for the topic. The focus is then placed on propagation from an outdoor transmitter to an indoor receiver at frequency bands aimed at personal communications and wireless local area networks. Penetration loss is measured at 1.8 and 5.8 GHz for various small scale wall and window structures. Empirical models have been evaluated for the dependence on incidence angle in order to provide a simple yet accurate model for the loss.
