description A wireless base station allows a mobile device to communicate with a wireless network. An estimate of the location of the wireless base station may allow a location based service to determine the location of a mobile device. In an embodiment, location may be estimated using a collection of data samples obtained from a mobile device. These data samples may contain carrier related timing information, for example GSM (Global System for Mobile Communications) timing information and received signal strength indication (RSSI). Data from the GSM timing information and RSSI may be analyzed to estimate a distance of a mobile device from a wireless base station. In another embodiment, a centroid of the data samples is computed. The centroid may then be used to estimate the direction of a cell phone tower relative to the centroid. In this way, using an estimate of distance and direction, location of wireless base station may be estimated.
