    Abstract: A method for generating a two-dimensional radio coverage map comprising a plurality of physical levels including a first physical level and a second physical level. The access point is located above the second physical level. A first radio coverage map comprising original points located at a first distance from the access point is generated. Each of the original points has a first predicted value. A distance is selected to place the two-dimensional radio coverage map at the target distance from the access point. Coordinates of map points of the two-dimensional radio coverage map are generated. Each of the map points corresponds to one of the original points. An offset value representing an attenuation due to the target distance being different than the first distance is computed. For each of the map points, a predicted received signal strength value is generated by adding the offset value to the first predicted value of the corresponding one of the original points.

    Abstract: In a tracking of a position and motion of a device, a set of hypothetical locations of the device is generated. Hypothetical locations among the set are propagated to respective hypothetical next locations, using respective location-specific propagation models associated with the hypothetical locations. Sensor information having correlation to a location of the device is received. An importance weighting for the hypothetical next locations is calculated using the new sensor information. Probable locations of the device are generated using the importance weighting.

    Abstract: A visual beacon, such as a Quick Response (QR) code or other type of artificial visual beacon is identified based on a coarse position and content information, and optionally, type of the visual beacon. For example, position may be based on latitude and longitude, e.g., from a satellite positioning system, or the CellID from a cellular network. The content information may be based on a sampling of the content before or after decoding. Content information may alternatively be all of the decoded content or an image of the visual beacon. Thus, for example, a mobile platform may generate a visual beacon identifier using the position and content information, which is transmitted to a navigation assistance server. The server can access and transmit to the mobile platform a navigation assistance message associated with the visual beacon identifier. If no visual beacon identifier is found, the server may enter the information.
