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 the objective wireless terminal in respective position detectable areas before eventually determining the actual position of the objective wireless terminal.
