System and method for wireless location performance prediction

A system for performance analysis of a location system comprising:

• means for storing data related to location equipment, wireless infrastructure, handsets and terrain;
• means for generating a site file for predicting path loss and predicting time/angle error based on the stored terrain data;
• means for computing multi-site forward and multi-site reverse link signal strengths for determining coverage, of the location system;
• means for generating multi-sire margin data and multi-sire delay/angle error data from the computed multi-site forward and reverse link signal strengths and the stored data;
• and
• means for generating location error estimates for the wireless location system from the predicted delay/angle error data.

A method for analyzing performance of a wireless location system comprising:

• storing data related to location equipment, wireless infrastructure, handsets and terrain;
• generating a radial model and a radial map including a plurality of radial paths for a site from stored data;
• selecting a propagation model from a stored plurality of propagation models for predicting a path loss along each radial path;
• predicting accumulated angular errors and time delay errors at each point along a radial path in the radial map;
• and
• generating an error estimate from the accumulated angular errors and the time delay errors due to terrain and morphology.
