A multi-wall-and-floor model for indoor radio propagation

A requirement for the performance evaluation of wireless systems by means of simulations is the knowledge of the path loss between transmitters and receivers. A new indoor path loss model for large-scale attenuation is proposed The multi-wall-and-floor (MWF) model considers the nonlinear relationship between the cumulative penetration loss and the number of penetrated floors and walls. The model has been derived from ray tracing simulations in different scenarios and the respective parameters are provided at 5.2 GHz. For validation purposes, measurements and extensive comparisons with results found in literature have been performed. The simple structure of the MWF model makes it an interesting alternative to ray tracing for system simulations in indoor environments.
