Abstract :
This paper uses the results of a calibrated ray tracing software in a sample office environment to analyze and model the distance error measured from the estimated time of arrival (TOA) of the direct line-of-sight (LOS) path in a typical indoor environment. First, we analyze the effect of bandwidth on the measured distance error using TOA and then, we propose a model for simulation of the distance error in LOS and OLOS indoor areas.
