Indoor positioning using ambient radio signals: Data acquisition platform for a long-term study

This paper presents an ongoing long-term study exploring indoor positioning systems based on ambient radio signals (such as FM, TV and GSM). We introduce an open-source platform designed to facilitate data acquisition in indoor localization experiments. The platform is currently employed for the creation of a public dataset of geo referenced ambient radio signal samples. The paper discusses the system design as well as the challenges and current lessons of the year-long experiment.
