摘要： Embodiments of the present invention are directed to determining the geographic location of network entities. An embodiment is a method of determining the geographic location of a host including, identifying at least one gateway communicatively coupled to the host, determining a geographic location of the at least one gateway based upon a proximity relationship between the gateway and a localizable entity, and determining the geographic location of the host based upon the determined geographic location of the at least one gateway. Another embodiment is a method for a host to determine its geographic location by determining reachability information to communicatively coupled network entities, sending the reachability information to a location server, and by receiving geographic location information from the location server.

摘要： Systems and methods are provided for estimating the locations and coverage ranges of wireless transmission stations based on the existing location and coverage range data. The system divides the transmitting stations into a plurality of pairs and estimates new coverage range and location for each transmitting station in each pair based on confidence level, distance to another transmitting station in the same pair and coverage range overlap with other transmitting stations. Systems and methods are provided to estimate the location and accuracy range of the location of a client device based on the intersections of the coverage ranges of wireless transmission stations detected by the client device. The system repeatedly removes the transmission station with fewer number of intersections from further process if the number of intersections for each remaining transmission station is not the same.
