Abstract

Propagation effects are studied within buildings to examine their influence on the performance of wideband communications systems that might operate under the FCC ultra-wideband (UWB) and IEEE802.16 specifications. In this ray-tracing and finite difference time domain (FDTD) techniques are used to consider propagation in the light of changing building techniques. Data from this is seen to agree quite well with measured data available in the literature, and identify propagation mechanisms and characteristics. In an indoor point to multipoint scenario involving line of sight and non-line of sight propagation a multiband frequency diversity scheme appears to show much promise.
