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