System and method for predicting location accuracy of a mobile unit

A method of assigning geographical coordinates to a calibration point located in a geographic region for the location of a mobile device comprising the steps of:

• (a) providing configuration information for a geographic region;
• (b) estimating one or more expected characterizing parameters of a network measurement report (“NMR”) associated with a hypothetical mobile device at each of one or more calibration points in the geographic region;
• (c) for each of said calibration points:
• (i) evaluating the expected characterizing parameters;
• (ii) determining if at least one grid point should be defined based on said evaluation;
• and
• (iii) assigning geographical coordinates to said at least one calibration point.

A method for generating a model for deployment of a geolocation system in a geographic region comprising the steps of:

• (a) providing configuration information for the geographic region;
• (b) estimating signal parameters in the region as a function of mobile device location in the region;
• (c) determining an approximate statistical accuracy of a signal pattern as a function of the estimated signal parameters in the region;
• and
• (d) modeling an expected accuracy of the geolocation system in the region as a function of the configuration information and determined approximate statistical accuracy.
