Modeling wireless channel delay spread trends

Wireless channel measurement and modeling is increasing in sophistication in order to more accurately account for channel effects upon communication signals. In this paper we provide an analysis of measured delay spread trends in an outdoor environment in the 5 GHz band. We quantify the increase in delay spread when making a transition from line-of-sight to non-line-of-sight regions. This information may be of use in future high performance adaptive communication systems that work to ldquoanticipaterdquo channel changes, and for the creation of future wireless environment maps.
