1. A method of testing network-based location determination technologies within a single test area in the field comprising:

  • determining a site within which signal transmitter and receiver locations are known;

    defining scenarios representative of propagation impairment conditions;

    modifying, within the site, parameters of transmitted and received signals to simulate propagation impairment conditions based on the defined scenarios;

    executing location determination technologies to estimate a geographic location of a transmitted signal; and

    evaluating the performance of location determination technologies by comparing the estimated geographic location to the known transmitter location.
