Empirical calculation of shadowing deviation for complex indoor propagation topologies at 2.4 GHz

This paper presents an empirical calculation of shadowing deviation for complex indoor propagation topologies at 2.4 GHz. Based on measurements acquired in a complex indoor propagation environment (the premises of wireless telecommunications laboratory) at 2.4 GHz, a site-specific validation of indoor RF models was conducted. Expanding this recent work, the shadowing deviation is calculated (in dB) based on the losses caused by all different types of walls and floors interfering in the signal path. These losses are acquired by the multi-wall-floor model that provides significant precision regardless of the complexity of the indoor topology in question. The calculation of the shadowing deviation is therefore established in a concrete manner. This method is not limited at 2.4 GHz but can be applied in any other frequency as well, as long as the losses for all types of walls and floors that come into consideration will be provided or empirically calculated.
