Effects of wall-angle distributions in indoor wireless communications

Providing broadband wireless access in indoor scenarios with multiple indoor transmitters is largely influenced by the blockage of the signals by walls. In this paper, we propose a mathematically tractable approach that relies on stochastic geometry for the distribution of walls in randomly generated scenarios, and investigates on the influence of different distributions of wall orientation angles as well as the influence of the transmitter arrangements. We outline the limited insights that can be obtained by random shape theory and propose the concept of effective wall attenuations to compensate for the remaining deviation from the actual results. The validity of our approach is verified by extensive Monte Carlo simulations.
