Abstract
A method for determining a geo-location of a target station is provided. The method includes receiving a plurality of RTTs over a plurality of successive time intervals. Each successive time interval is equal to a predetermined amount of time. The plurality of RTTs is placed into a plurality of bins. Each bin has a predetermined time width and a count of RTTs placed in the bin. A bin with a highest count of RTTs (maxCb) and another bin with a next highest count of RTTs are selected and a maximum count ratio determined. The bin with maxCb to a maximum bin value is set based at least on a predetermined threshold of the maximum count ratio. During a next successive time interval, the RTTs that are placed in the bin that is set to the maximum bin value are selected to determine the geo-location of the target station.
