Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses to allow for location related information for a region of space within a structure to be divided into blocks and selectively provided in an efficient manner to a mobile station and/or a proxy device associated therewith. The mobile station may, for example, use the blocks of location related information to support signal-based position estimation and/or other like location based services.

Abstract: Apparatuses and methods for adjusting wireless-derived positions of a mobile station using a motion sensor are presented. One method includes estimating a position of a mobile station based upon wireless signal measurements and measuring a movement of the mobile station using a relative motion sensor. The method further includes detecting a displacement of the mobile station based upon the measured movement, determining that the displacement is below a threshold and then adjusting the estimated position of the mobile station using information from the relative motion sensor. An apparatus includes a wireless transceiver, a relative motion sensor, a processor coupled to the wireless transceiver and the relative motion sensor, and a memory coupled to the processor. The memory stores executable instructions and data for causing the processor to execute methods for adjusting wireless-derived positions using a motion sensor.

Abstract: The subject matter disclosed herein relates to utilizing location information, such as maps, in location determination based on Received Signal Strength Indication (RSSI) and Round-Trip Time (RTT) data. Weighting information can be determined from and/or provided in the location information. The weighting information associated with an area in which a mobile device is located can impact how RSSI and RTT data is weighted in a calculation of the mobile device's location.

Abstract: The subject matter disclosed herein relates to systems, methods, apparatuses, devices, articles, and means for updating radio models. For certain example implementations, a method for one or more server devices may comprise receiving at one or more communication interfaces at least one measurement that corresponds to a position of a first mobile device within an indoor environment. At least one radio model that is stored in one or more memories may be updated based, at least in part, on the at least one measurement to produce at least one updated radio model. The at least one radio model and the at least one updated radio model may correspond to the indoor environment. The at least one updated radio model may be transmitted to enable a second mobile device to use the at least one updated radio model for positioning within the indoor environment. Other example implementations are described herein.
