Abstract
A method for calculating the geographical position of a user equipment (UE) unit includes collecting position parameters conveying the relative position of the UE unit from two or more base stations using technologies mandated for the modern wireless networks. Particularly, know (predetermined) signals embedded in the downlink and uplink subframes, such as preambles, pilots, ranging codes are used for determining the coordinates of the UE unit. In addition, the methods and systems proposed here take advantage of the multiple antennas systems mandated at both the UE and BTS.
