Abstract

Penetration of wireless transmission into buildings has been discussed widely within the context of wireless coverage, and mainly for the 800-900 MHz and 1800 – 2000 MHz bands. The application of MIMO communications raises another aspect of the penetration: the paths' correlation and the respective "richness" of the incoming signal. This memo portrays a strategy of investigation into this issue. Each of the penetration mechanisms is addressed separately and a simple model is sought, in pursuit of characterizing the integrated effect by a limited number of parameters. Propagation models Fig.1 : propagation modes The following propagation modes and models thereof are to be discussed (Fig. 1): 1. Sources of waves impinging on the outer wall a. Direct (LOS) b.
