Abstract
In this paper, we present building entry loss (BEL) measurements on a line-of-sight (LoS) and non-line-of-sight (nLoS) path at 3, 6, and 10 GHz. To investigate impacts of reflected energy (RE) from surrounding environments on the BEL and whole propagation loss, measured and analyzed results are presented according to the presence or absence of the large clutter (a training ship) behind the building. A new parameter RE is proposed for the path loss prediction in the nLoS path and its value is extracted using the measurement results. As a result of the analysis, it was proved that accurate path loss prediction is possible by adding an excess loss (EL) to the sum of clutter loss (CL) and BEL. Therefore, the proposed RE should be considered as a parameter to predict the received power indoors on the nLoS path. Finally, RE measurement and calculation methods are proposed.
