Abstract: Methods, apparatus, and computer program products for determining a mobile device location. An example of a method for determining a mobile device location includes receiving signals from a transmitter, measuring signal characteristics of the received signals, and downloading data from a database corresponding to a defined region associated with the transmitters. The downloaded data includes a set of position points, a classification of each position point, and expected signal characteristics for each position point. The method further includes comparing the measured signal characteristics with the expected signal characteristics for each position point, assigning a weight to position points based on the compared signal characteristics, and determining the mobile device location by selecting one position point from the set as a position point solution corresponding to the mobile device location based on the assigned weight. The position point solution is constrained by the classification of each position point.

Abstract: A computer-implemented method for converting a raster image map to a vector image map includes receiving an electronic raster image that shows an indoor map of a building structure. The method also includes determining whether the indoor map is a line map. If not, the indoor map is converted into a line map. Next, the electronic raster image is processed to generate a processed raster image of the indoor map. The method then extracts vector lines from the processed raster image to generate an electronic vector image that includes the indoor map of the building structure.

Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media enabling rogue access point detection with a communications device by sending multiple probes via different network connections to a remote server and receiving probe replies. Various embodiments may include a communication device transmitting a first probe addressed to a server via a first network connection and a second probe addressed to the server via a second network connection. Upon receiving a first probe reply from the server via the first network connection and a second probe reply from the server via the second network connection server, the communications device may analyze the received probe replies to determine whether an access point of either the first network or the second network is a rogue access point.
