Abstract

Location ¯ngerprinting utilizes periodic beacons transmitted by Wireless Local Area Network (WLAN) Access Points (APs) to provide localization in indoor environments. Currently there is lack of methods to quantify the amount of localization information provided by individual APs. Such a metric would enable the optimal placement of new APs as well as filtering out excess APs so as to reduce the resources consumed by indoor localization software in client devices. This paper proposes Location Info, a metric that utilizes walk test data for quantifying the localization efficacy of APs. Simulation based studies shows that Location Info is able to accurately select APs with high localization information.
