Investigation of area spectral efficiency in indoor wireless communications by blockage models

Abstract

The performance of indoor wireless cellular networks depends on several parameters such as base station density or arrangement, as well as the blockage of the signal by walls. We investigate the dependence of the network performance in terms of coverage probability and also area spectral efficiency in order to demonstrate the influence of the base station density. We analytically derive expressions for both performance metrics including the blockage by walls and compare these results to those of extensive Monte-Carlo simulations. This is performed for different association strategies as well as for random and regular base station placements. It turns out that in general the addition of walls improves the network performance, and does so even more the smaller the base station density becomes.
