Abstract

To enhance in-building location determination of an electronic device, described is a system and a method that uses a blip access point to transfer location assistance information to the electronic device. The location assistance information may contain a map of dummy beacons that serve as reference points (e.g., landmarks) from which the electronic device may determine its location relative to the map information.
