Abstract

Provided is a method and/or apparatus for providing a wireless location service using a beacon signal. A wireless location service method may include collecting a plurality of beacon signals from each of a plurality of beacon transceivers positioned around a user, and determining a current location of the user based on at least one of a virtual point and the plurality of beacon signals, the virtual point positioned in a space in which the beacon transceivers are provided.
