Abstract: The disclosure generally relates to a method and apparatus for using a location token to locate a mobile device in a mapped environment. In one embodiment, the disclosure relates to identifying an AP in the environment using an AP location token. By finding a map from a map vendor which has a substantially identical map token, the AP and the map may be matched together. Once the AP is matched to the map, its exact location will be known. The location of a mobile device may be determined in relation to the AP's location. The same process may be used to identify the location of several APs on a map and thereby identify the location of the mobile device relative to the APs.

Abstract: Embodiments of a communication station and method for transmission power control for Time-of-Flight (ToF) measurements in a wireless network are generally described herein. A protocol for fine timing measurements (FTMs) optimizes location performance rather than Wi-Fi coverage area and bit error rate by limiting an allowed maximum power and hence, EVM. A user equipment (UE) comprises a transceiver configured to receive, from an initiating station, a fine timing measurement request (FTMR) message at a maximum transmit power and lowest modulation and coding scheme (MCS), measure a relative received signal strength (RSSI) for the received FTMR message, determine a maximum transmit power, where the maximum transmit power is proportional to the measured RSSI; and transmit, to the initiating station, a fine timing measurement 1 (FTM1) message at the determined maximum transmit power and received lowest MCS.

Ranging may use a time-of-flight (ToF) process, and may compensate for multipath interference. Trilateration may consider relative accuracies of ranging components. Other examples are described and claimed.

Abstract: Embodiments of a system and method for Access Point Location Discovery in Unmanaged Networks are generally described herein. When a device attempts to discern its location indoors, it must be aware of the exact location of the network infrastructure that participates in the measurement. Indoors, it is the location of the Access Points (APs), which must be known to the device in order to triangulate its position. A system and method are disclosed for correctly discovering the exact location of network APs. An AP populates a neighbor list with location information by performing Wi-Fi scanning to receive a Media Access Control address and radio channel of a neighboring AP. The interested AP then acquires the position of this AP neighbor by querying its location and receiving its position information. Lastly, the received neighbor location is validated for correctness and reliability using Time of Flight measurements.

Abstract: Embodiments of a system and method for Access Point (AP) initiated time-of-flight positioning in a Wireless Network are generally described herein. A precise scalable network initiated Time-of-Flight (ToF) solution for indoor positioning and navigation is provided for environments where global-navigation-satellite-systems signals are not available. ToF between an initiating AP and a responding device is measured and converted into distance by dividing the measured time by two and multiplying it by the speed of light. The AP, rather than the client, fully controls the timing and management of the overall indoor location procedure. The Fine Timing Measurement portion of the Access Point Initiated ToF Positioning protocol is a symmetric protocol such that measurement of the ToF is readily switchable between the client and the AP.
