A New Metric to Analyze Propagation Models

Abstract

Abstract-Deterministic propagation models are typically validated by performing comparisons between real and simulated E-field envelope distributions. These distributions correspond to straight spatial segments and, occasionally, also surfaces. This approach is correct to study large scale fading for relatively large distances. However, in a real environment and shorter distances, there are too many details to consider. As a result, it is almost impossible to reach a point by point match in a minimally realistic experiment. There are two ways to deal with this problem. The first one is to model every minor detail everywhere around us, keeping the point by point metric. The second one is to change that metric in order to admit, at least in part, that we can not take into account of all the details. If uncertainty can not be eliminated, we should learn to take advantage of it by using a statistical metric like the one proposed here. This paper uses such a kind of metric to validate several structural and geometrical simplifications of a model for the transition between outdoor and indoor propagation that has been recently published. Furthermore, we demonstrate that this metric has helped us to improve and understand better this model, while revealing unexpected model properties at the same time.

Evaluation of Electromagnetic Dosimetry of Wireless Systems in Complex Indoor Scenarios With Human Body Interaction

“…Deterministic methods [41][42][43][44][45][46][47] are based on numerical approaches to the resolution of Maxwell's equations, such as ray launching and ray tracing, or full-wave simulation techniques (method of moment (MoM), finite difference time domain (FDTD) [48], FITD, etc.). These methods are precise but are time-consuming to inherent computational complexity.…”

Analysis of Wireless Sensor Network Topology and Estimation of Optimal Network Deployment by Deterministic Radio Channel Characterization

“…Various indoor models have been developed in the past based on semi-empirical approaches [10][11][12]. The advantage of these methods is that they require low computational cost but they have limited accuracy in comparison with high precision full wave techniques, which also exhibit very high computational cost [13][14][15][16][17][18][19]. A commitment between accuracy and computational time is acquired with deterministic methods, which are based on Geometrical Optics [20].…”

Effect of Ionospheric Induced Depolarization on Satellite Solar Power Station

“…Research on delivering energy from space to earth started at the Institute of space of Astronautical science [ISAS] in 1981 and there has been an annual space energy symposium at ISAS since then. As part of working of this group "Solar power satellite" Strawman project was conceptualized [2].…”

“…Deterministic were typically validated by performing comparison between real and simulated E-field envelope distribution [2]. Theoretical analysis of non linear interaction of intense electromagnetic wave and plasma waves In ionosphere and numerical estimation of SSPS microwave impact on ionospheric environment were also discussed [3,4].…”
