Abstract: Disclosed are a system, apparatus, and method for adaptive discovery and scanning of wireless access points. In one embodiment, a set of channels can be scanned in a first iteration to discover wireless access points. In one embodiment, a discovery profile based on the discovered wireless access points can be determined and in a second iteration, a subset of the set of channels can be scanned. In one embodiment, the subset consists of non-overlapping channels selected according to the discovery profile.

Abstract: A method of obtaining and using access point signal information includes: receiving signals at a mobile device from a first set of access points during a passive measurement; and performing a first active measurement at the mobile device for the first set of the access points, including: sending at least one first communication each sent toward a respective one of the access points of the first set; and receiving at least one second communication each corresponding to, and responsive to, one of the at least one first communication and received from a corresponding one of the access points of the first set; where the passive measurement and the first active measurement is each performed repeatedly with the first set of the access points being reestablished at each repeat performance of the passive measurement, and with the passive measurement being performed less often than the first active measurement.

Abstract: Disclosed are systems, methods and devices for application of determining position information for mobile devices. In specific implementations, measurement of a signal travel time and a signal's strength may be combined to characterize a transmission power of the signal's transmitter. The characterized transmission power may be applied to affect expected signal strength signature values for use of the signal's transmitter may be updated in order to enhance a location based service where location may be effected by accuracy of a transmitter's power.

Abstract: Techniques are provided for providing a processing delay estimate of an access point, or turnaround calibration function (TCF), associated with round trip time (RTT) measurements. Mobile devices, access points, and/or other systems can utilize these techniques to derive processing delay from the RTT measurements. Crowdsourcing can also be used to help increase the accuracy of the processing delay estimate, which can be propagated to multiple devices.

Abstract: A method for locating a target transceiver in a wireless communication system includes: obtaining at least one scan list indicating a set of transceivers including the target transceiver; identifying, from stored geotagging data, locations of at least some previously located transceivers represented in the at least one scan list that are distinct from the target transceiver; generating a list of neighbor transceivers corresponding to the target transceiver based on the at least one scan list; and calculating an estimated location of the target transceiver using the list of neighbor transceivers and the locations of the previously located transceivers represented in the at least one scan list.
