In the world of cellular surveys, sometimes it is necessary to not only know what base station and what channels are there, but also where are the base stations geographically.
QRC has developed several methods both passive and active for analyzing collected data and predicting the locations of emitting base stations.
QRC's New Passive Base Station Location (PBL) software tool is our latest technology for predicting Tower Location. Using TDOA, we are able to make constant measurements on each base station we are measuring. Through the use of the internal, high speed scanner present in each ICS product, PBL is able to make calculations on base station location at each geographical coordinate. Combining all those measurements together, allows us to plot base station locations very accurately.
PBL supports CDMA, GSM, WCDMA, EVDO protocols.
