Allowing guests of entertainment parks or at cruise liners to localise themselves is an interesting technical challenge and important for new types of wireless services. Such geolocation is typically based on cellphone determining their locations with the help of GPS or cellular base stations. Drawbacks of GPS are high battery consumption and the need for a clear view of the sky, making it impractical at cruise liners, in indoor areas, tree-covered zones, or similar environments where obstacles shadow the GPS signals. Approaches using the cellular network are not reliable and precise enough. In this project, we look at various technologies to improve the reliability of the geolocation services. We develop a station identity management system that preserves base station location privacy. The objective is to allow only authorized parties to obtain the locations of guests. We further investigate ways to exploit Wi-Fi time-of-flight measurements for precise and reliable localization.
