Abstract:
Methods and systems for providing virtual beacons are presented. According to one aspect, a method for providing a virtual beacon at a first location comprises transmitting, by a transmitter at a second location geographically different from the first location, an information signal using a transmit power level, Pj, and including an advertised transmit power level, PA, both selected to be indicative of a distance, d, between a location of a receiver of the information signal and the first location. The signal transmitted from the second location emulates a signal that would have been produced by a beacon located at the first location. The information signals may be aimed at one or more User Equipments (UEs), and/or may be focused on one or more specific target locations rather than on individual UEs.
