Abstract

In this paper, we predict the propagation characteristics of indoor radio waves at 2450 MHz frequency set up in an office building. Based on a time domain finite difference algorithm, a numerical model of a single floor of the simulated office building gives the relationship between the office environment and the propagation characteristics, and the calculated received signal strength indication (RSSI) distribution and path loss at 2450 MHz frequency are discussed. It is clarified that the path loss increases due to the presence of internal obstructions. In addition, the RSSI distribution in the observation plane indicates that the higher the complexity of the indoor spatial environment, the weaker the transmitted power of the signal.
