摘要： Various methods, apparatuses and/or articles of manufacture are provided which may be implemented in one or more electronic devices supporting mobile device positioning within an indoor environment. Tiered positioning assistance data (tiered-PAD) corresponding to an indoor environment may be generated and/or distributed. Mobile device positioning and/or navigation capabilities may be based, at least in part, on tiered-PAD corresponding to the indoor environment. Tiered-PAD may be provided to a plurality of mobile devices. A given mobile device may, for example, select applicable portion(s) of tiered-PAD to affect one or more positioning functions and/or the like which may be performed, at least in part, by the mobile device.

摘要： Methods, devices, and systems are described for determining whether a mobile device is in a stopped state based at least in part on round trip time (RTT) measurements between the device and at least one access point. The stopped state determination may be based on RTT measurements alone, or on RTT measurements in combination with other positioning and movement measurements. Further, filtering such as particle and Kalman filtering may be used to improve determination of whether the device is in a stopped state.

摘要： Methods, devices, and systems are described for determining whether a mobile device (110) is in a stopped state based at least in part on round trip time (RTT) measurements (122a, 122b, 122n) between the device and at least one access point (120a, 120b,..120n). The stopped state determination may be based on RTT measurements alone, or on RTT measurements in combination with other positioning and movement measurements. Further, filtering such as particle and Kalman filtering may be used to improve determination of whether the device is in a stopped state.

摘要： Methods, systems, computer-readable media, and apparatuses for determining a location for a wireless communication device using an integrated WiFi sniffer and measurement engine are presented. The method includes utilizing a first WiFi transceiver and a second WiFi transceiver. Data communications or positioning communications can be transmitted and received on either of the first and the second WiFi transceivers, or both.
