Claim:
1. A method of determining the location of a wireless terminal, the method comprising: accessing a first access point antenna radiation model generated from measurements of a first antenna radiation pattern of a first access point antenna or generating the first access point antenna radiation model from a computer model of the first access point antenna; performing a multipath correction to the first access point antenna radiation model to correct for multipath effects which are expected in an actual physical environment where the first access point antenna is to be deployed as part of a first access point, said multipath correction producing a first location adjusted access point antenna radiation model; generating a first probability surface from said first location adjusted access point antenna radiation model, said first probability surface corresponding to the first access point for a first received signal strength, the first probability surface indicating multiple different location probabilities when a signal is received from the first access point at said first received signal strength; and generating, based on at least said first probability surface a first wireless terminal location estimate for a wireless terminal reporting receipt of a signal from said first access point having said first received signal strength.
