Abstract:
1. A method for collecting and processing uplink received signal level data and downlink geolocation data over a wireless system, comprising the steps of: gathering signal strength data of received uplink signals of subscriber mobile units as measured and collected by a cell site, the mobile units being in active communication with the cell site and using an active communications channel of the wireless system; gathering downlink geolocation data corresponding to the mobile units, the downlink geolocation data measured by the mobile units; forming data pairs by identifying the gathered geolocation data and the gathered signal strength data corresponding to the same mobile units and by selecting the geolocation data and the measured signal strength data received within sufficiently close temporal proximity to a reference time stamp to identify data from the same mobile unit; generating a set of data pairs correlating measured signal strength values to specific geographic locations throughout said wireless system; and analyzing said generated set of data pairs to evaluate system performance within said wireless system, wherein each of the steps are performed without drive testing.
