Statistical Modelling of the Delay Spread of the WBAN channel Considering Room Geometry and Material Characteristics

Abstract

This communication presents the development of Delay Spread statistical models of the Wireless Body Area Network indoor channel taking into account parametrically the geometry and the material characteristics of the rooms within the framework of a scenario-based approach in the UWB (Ultra Wide Band) context. The study is performed in the 1 st UWB subband B = [3.1, 4.8] GHz and restricted to the stationary (timeinvariant) channel, the subject being motionless. The models are derived from statistical samples obtained thanks to a homemade simplified Ray-Tracing code. The trends of the simulations were compared to the behavior of the Delay Spread of the "classic" indoor channel observed in several experimental studies (for different frequency bands), which confirmed the reliability and consistency of our approach. The models extracted from a set made up of several categories of premises present a very satisfactory goodness of fit for the three considered radio links.
