An Empirical Path Loss Model for Indoor Environments in 2.4GHz 802.11n Networks

Abstract

Various indoor models based on the femtocell deployment have been proposed in the literature. However none of the schemes provides a generic model for the indoor propagation, because some important parameters are missing related to the wall and floor effects scenario. All existing schemes considering only the thickness of wall and does not consider the ceiling height for the different floor effect. However the proposed new scheme takes materials of wall and no longer to thickness for the wall scenario in indoor propagation model. And, it is also considering the total height difference between the user equipment and access point for the floor scenario. By taking these parameters, in terms of mean absolute error, the proposed scheme has better performance than all other existing models. All the schemes were tested in a three-story building with different number of penetrated walls and floors.
