Luckily, it is impossible to get more accurate location with only a cell tower triangulation, GPS will be required. Google displays a vague circle area representing the zone covered by the primary cell tower thats in contact with the phone. This geometric calculation applies in the case of cell phones, since we know the locations of the cell towers which receive the phones signal, and we can estimate the distance of the phone from each of those antennae towers, based upon the lag time between when the tower sends a ping to the phone and receives the answering ping back. Please see E911 white papers at http://www.sunsight.com. In three dimensional space, when two spheres intersect, you get a circle.
