A method and system for collecting test and measurement data for a
wireless communication system utilizes a network overlay geo-location
system to collect the data. The wireless communication system has plural
base stations defining a signal coverage area for communication with a
mobile appliance and collects test and measurement data simultaneous on
the forward and reverse links during standard geo-location processes. The
wireless communication system also collects test and measurement data
when the network overlay geolocation system is in an idle state.
