3D indoor location and navigation system based on Bluetooth

Over last years, Indoor Positioning and Navigation Systems (IPNS) has been subject of intense study and research ought to it has become a blind spot with regard to Positioning and Navigation Software. None of proposed indoor solutions has been as successful as outdoor systems like Global Position System (GPS). Our proposal presents the design and implementation on mobile device(the most common), of a 3D positioning and navigation system for indoor based on the use of Bluetooth (BT) radio technology and implemented using Java and J2ME, this implementation is adaptable to whatever indoor environment (commercial centers, offices, museums, etc.) previously modeled and loaded. This 3D model can be build using the most common 3D design tools with M3G formats support. Location is implemented on BT with distributed estimation (the mobile device performs it).
