Building the basic concept of a low cost, robust, indoor positioning system based on magnetic resonant coupling that we have presented in previous work we describe our entry into the EVAAL indoor location competition. The ba- sic physical principle behind the system makes it extremely robust as the signals are hardly influenced by the human body or objects in the environment (except massive metal objects which however have mostly local influence only). Going beyond previous work we provide a detailed description of the processing archi- tecture, show how the system can be set up on the basis of the floor-plan alone (no location specific training or measurements needed), present the software tools that can be used for system setup and application and evaluate floor plan based setup looking specifically into the influence of multiple people and changes in furniture configuration.
