Facilitation of determination of antenna location

Abstract

Assisted global positioning system (AGPS) information is retrieved from mobile devices and employed to facilitate antenna location. Measurement information, including AGPS information, can be received from a plurality of mobile devices dispersed over a geographical region. The measurement information can include location and timing information for the plurality of mobile devices. A timing difference between co-located antennas of a base station associated with the plurality of mobile devices can be computed. The location of the co-located antennas can be determined based on evaluating errors resultant from estimations based on a plurality of test locations. The measurement information can be aggregated over time and can be employed to update the antenna locations.
