Abstract
An apparatus for wireless positioning includes a first delimitation unit configured to delimit an initial boundary for a predetermined space to divide the predetermined space into at least two areas, each area of the at least two areas comprising multiple zones, the multiple zones including a boundary zone adjacent to the initial boundary; a detection unit configured to detect signal feature values of respective wireless access points in the boundary zone and determine an identifier set of the detected wireless access points; and a second delimitation unit configured to re-determine the boundaries of the at least two areas for the wireless positioning based on the detection results in the boundary zone. With the method and apparatus of embodiments of the present invention, it is possible to reduce the positioning calculation time while maintaining high positioning accuracy.
