Abstract: Embodiments include using a wireless access point (AP) as a landmark to aid precise wireless indoor positioning of a mobile device. The AP transmits a wireless indoor positioning signal with a predetermined or known frequency and power that is typically only able to be detected and decoded by any of various types of mobile devices that are within a predetermined “close” range of the AP. Based on positioning the mobile device within the predetermined range, the device may calibrate one or more physical sensors of the mobile device for indoor positioning. Such wireless landmarks provide more accurate, efficient, automated and reliable wireless indoor positioning and sensor calibration.

Abstract: Systems, apparatus and methods for determining whether to use an indoor map or an outdoor map based on local area network (LAN) signals from access points (APs) are disclosed. If only weak AP signals belonging to a location content identifier (LCI) are received, prior art systems display an indoor map associated with the LCI. An improvement herein further determines a quality of AP signals and/or wide area network (WAN) signals before determining whether to display the indoor map or an outdoor map.
