Claim Text:
1. A method of estimating the location of a wireless terminal, the method comprising: receiving, by a computing device, the identities of one or more radio signals that are received by the wireless terminal; estimating, by the computing device, a probability that the wireless terminal is indoors based on i) the identities of the one or more radio signals that are received by the wireless terminal and ii) a characterization that is a composite that accounts for a) the amount of unique identities that have appeared over a predetermined interval and b) the area of a convex hull spanned by the locations of radio signal sources, wherein the unique identities are of radio signals that have been received by a plurality of wireless terminals; and transmitting, by the computing device, an estimate of the location of the wireless terminal to a device that is configured to execute a location-based application, wherein the estimate of the location of the wireless terminal is based on the probability estimated.
