Abstract
The approximate location of a directed cell of a cellular network is calculated based on locations in the vicinity of which mobile devices were able to detect the directed cell. A mobile device is able to estimate its own location from the approximate locations of one or more directed cells that it can identify. This estimated location of the mobile device may be used to seed its GPS receiver.
