    Abstract: Example methods, apparatuses, or articles of manufacture are disclosed herein that may be utilized, in whole or in part, to facilitate or support one or more operations or techniques for utilizing a reference signal for indoor positioning, such as for use in or with a mobile communication device, for example. In an implementation, a reference signal may be focused into a directed beam, for example using a phased antenna array, and rotated electronically through a sequence of directional angles in a horizontal plane. A mobile device may determine a most probable directional angle from one or more transmitters transmitting a directional beam, measure one or more parameters for each directional angle and determine a location estimate using, for example triangulation.

    Abstract: A computer-implemented method for detecting a boundary of a building from an indoor map includes providing an electronic raster image of the indoor map. A floor plan included in the map is a first color and a background of the image is a second color. The method includes scanning the image a first time in a plurality of directions and coloring pixels of the image a third color as they are scanned the first time until a pixel is detected that is not the second color. Then the image is scanned a second time in at least two directions. The second scan includes marking a pixel a fourth color for each third color to non-third color and each non-third color to third color transition. The resultant pixels of the fourth color represent the boundary of the building.

    Abstract: Disclosed are methods, systems and devices for providing location based services in a venue. To estimate its location, in a particular implementation, a mobile device may obtain a measurement of a range to a transponder device positioned at a known location based on measurements of a signal round-trip time (RTT) in a message exchange with the transponder device. Positioning assistance data from a server may enable the mobile device to measure a delay at the transponder device in providing a response to a probe message to thereby more accurately measure the signal RTT.
