Abstract: A method and system for testing network-based location determination technologies within a single test area in the field. Channel models are developed to simulate the propagation impairment conditions associated with identified test scenarios. The channel models for an identified test scenario can be developed by estimating the amount of multi-path, path loss, and Doppler frequency shift effects one would expect under the conditions and environment of the identified tests scenario. The path loss effects of an identified scenario may be estimated by combining the Okumura-Hata outdoor path loss models with available indoor path loss models. A single test area having receiving antennas and signal transmission of fixed and known geographic locations may be selected.
