Title:
POSITIONING METHOD AND POSITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/204243
Kind Code:
A1
Abstract:
[Problem] To provide a positioning method, positioning system, and positioning server capable of accurately detecting the position of a wireless terminal that moves in an indoor space. [Solution] The present invention is a positioning method that receives a probe request frame from a wireless terminal moving in a position measurement space by at least three access points with known coordinate values that are provided in the position measurement space and that positions the wireless terminal with the RSS value of the received probe request frame, wherein the method autoadaptively finds with the RSS value of a beacon frame that is sent and received at a predetermined interval between the access points an approximate curve that expresses the relationship between the RSS value and distance, selects at least three of the access points, applies the RSS value of the probe request frame received by the access points to the respective approximate curve obtained just prior, and determines the position of the wireless terminal by a three-point positioning method.
