Wide-band indoor localization effectiveness in presence of moving people

Abstract

Recently, new standards have emerged in the telecommunication industry. These standards provide an open global specification that enables mobile devices to access and interact with information and services instantly. Paving the way to the emergence of new added-values services, these devices require more and more a localization agent. When deployed, these wireless resources have to operate in non-stationary propagation conditions and from outdoors to indoors. This paper concentrates on the evaluation of UWB radio signals used for localization, in presence of moving people modifying the indoor propagation channel. Different frequencies, bandwidths and densities of moving people are considered. Impacts of these parameters are evaluated on two different ranging methods: time of arrival (TOA) based and received signal strength (RSS) based.
