Abstract
A technique is disclosed for estimating the lateral location of a wireless terminal in a geographic region. The technique is based on the recognition that some three-dimensional locations of the wireless terminal are improbable, and that measurements of temperature and atmospheric pressure at the wireless terminal and outside can be used to determine which lateral locations of the wireless terminal are improbable.
