1. An apparatus for determining cell coverage in a region with reduced in-field propagation measurements comprising:

  • a cell phone or equivalent device comprising a code segment that obtains wireless signal strength and the global positioning system coordinates;

    a data base that comprises geographical features of the region; and

    a processor that comprises a non-transitory computer readable medium, comprising instructions stored thereon, that when executed by a computer having a communications interface, one or more databases and one or more processors communicably coupled to the interface and one or more databases, perform the steps comprising;

    predicting the number of measurements required to accurately characterize path loss in the region;

    oversampling a suburban and a downtown region from cell measurements that comprise signal strength and global positioning system coordinates to determine the path loss prediction accuracy of wardriving and crowdsourcing; and

    using a statistical learning framework to build a relationship between these geographical features and the measurements, thereby reducing the number of measurements needed to determine path loss accuracy.
