Titel
Wi-Fi coverage and propagation for localization purposes in permanently changing urban areas
Abstract
In the field of localization techniques satellite based systems needs to be supplemented. One approach is to use the commonly installed Wi-Fi base stations for position determination. Our project with the testbed Nuremberg is focused on using fingerprinting algorithms. Therefore a map of reference points is necessary beside a sufficient amount of Wi-Fi transmitters. Building up this map is expensive; Wi-Fi infrastructure and radio characteristics are changing constantly - This paper is about our monitoring of the Wi-Fi coverage and the evaluation of the data to identify the demand of updating the database and the influences of changes on the localization.
