Abstract
Systems and methods are directed to information exchange between a location point (LP) and a wireless device. A LP may include a network access point (AP) and/or a dedicated location entity. In one embodiment, supplemental location-related information of a LP including, but not limited to, a geographic location source, geographic location accuracy, geographic location update time, LP type, distance from another LP, and/or timing offset calibration accuracy, may be wirelessly transmitted from a LP to a wireless device.
