Abstract:	This paper describes an innovative approach to the modelling of multipath impairments in a commercial laboratory test environment for mobile telephones that provide a GPS positioning capability for both emergency call location and location-based commercial services. The authors describe the background driving a need for improved laboratory representation of real-world environments that would demonstrate to regulatory authorities that extensive testing in the field is largely unnecessary, reducing vendor costs associated with qualification of multiple models of phones. Eventual standardisation of the models proposed and the test methodology would also lead to a more accurate comparison of the performance of phones from different vendors. For a field test location, results from field data are compared with those simulated for that location using the mathematical models developed.
