Abstract
Examples of determining the position of a mobile device within a structure are disclosed. In one example implementation according to aspects of the present disclosure, a computing device may include a processor and a memory. The computing device may further include an extraction module stored in the memory and executing on the processor to extract from a location-based service data stream a signal measurement of the path loss between a mobile device and a plurality of radio nodes distributed throughout a structure. The computing device may also include a positioning determining module stored in the memory and executing on the processor to determine the position of the mobile device within the structure using a known location for each of the plurality of radio nodes distributed throughout the structure by performing a linear optimization using the extracted signal measurement of the path loss.
