Abstract
In any indoor location, whenever operating a wireless terminal position detecting system comprising a transferable wireless terminal, a plurality of base stations individually allowing a connection from said wireless terminal, and a plurality of wireless receiving stations individually receiving wireless signal from said terminal and base stations, there is a problem in terms of the provision of a method for minimizing positional detection error on the part of said wireless terminal and a method for practically realizing said method. Hence, to solve the above problem, the present invention provides a wireless terminal position detecting method featuring the function to evaluate the result of measurement against wireless signals from an objective wireless terminal received by individual wireless receiving stations based on a definition of a plurality of position detectable areas designating a geographic range required for detecting actual position of said objective wireless terminal and also based on another definition for specifying plural wireless receiving stations each being located at a predetermined known position allocated for individual areas for detecting actual position of…
