Abstract: A user terminal measures a location thereof. In a method for measuring a terminal location, the terminal measures received signal strength indicator (RSSI) values of signals received from a plurality of electronic devices deployed in a space. Then the terminal extracts a preliminary location of the terminal with respect to each of a plurality of predetermined algorithms by applying the plurality of algorithms to the measured RSSI values, identifies a first estimated location of the terminal by applying a predetermined weight to each preliminary location, identifies a second estimated location of the terminal using an output of at least one sensor, and determines a final location of the terminal, based on the first and second estimated locations.
