    Abstract: A device stores an indication of a current floor of a multiple floor building on which a device is located. The device measures signal strengths of signals received at the device from transmitters having known locations on the floors of the building. The device selects one of the multiple floors as a candidate floor based in part on the measured signal strengths. The device increases a confidence level associated with the indication of the current floor if the candidate floor corresponds to the current floor, and decreases the confidence level if the candidate floor does not correspond to the current floor. The device replaces the indication of the current floor with the candidate floor if the confidence level is below a threshold.

    Abstract: Embodiments of techniques and systems for dead-zone-location detection in wireless systems are described. In embodiments, a wireless device may be configured to receive radio signals and provide indicators that convey signal strength of received radio signals. The received radio signals are considered degraded when signal strength of the received radio signals is below a threshold level. The wireless device may also be configured to determine which dead zone the wireless device is currently located, in response to a determination that receipt of radio signals is degraded. Other embodiments may be described and claimed.

    Abstract: A method of generating wireless signal information includes receiving relative movement data generated by sensors and wireless signal data generated by a wireless signal module at a computing system, the sensors and module for detecting wireless signals located in a portable electronic device (PED). The method further includes generating landmark information at a landmark detection module based on the relative movement data, the sensor data and the wireless signal data. The method further includes generating a plurality of Simultaneous Localization and Mapping (SLAM) estimate locations based on the landmark information and the relative movement data at a SLAM optimization engine. The method further includes assembling a first database of locations and corresponding wireless signal strength and access points. The method further includes generating additional information concerning locations and wireless signal information based on the first database.
