Indoor Radio Propagation Models



The paper presents the importance to characterize the indoor radio propagation channel to ensure satisfactory performance of a wireless communication system. Site measurements can be, sometimes very expensive; propagation models have been developed as suitable low-cost alternatives. The existing models can be classified into two major classes: statistical model and site-specific models. In this paper, we present a short review of the existing developments in the indoor propagation models, followed by the discussion of two models, a new empirical model, and a ray-tracing model, both incorporating additional phenomenona suggested by electromagnetic field techniques. Comparisons of our predicted results to measurements indicate that improvements in accuracy are achieved.
