Abstract: A method and a system for wireless positioning are provided. Multiple received signal strengths corresponding to multiple wireless access points are measured by a user device. The received signal strengths include multiple first received signal strengths. A reference positioning position is obtained according to positioning reference information provided by the user device. A first positioning position based on the first received signal strengths is obtained. The reference positioning position is compared with the first positioning position. In response to the distance between the reference positioning position and the first positioning position being greater than a tolerance value, at least one of the first received signal strengths is excluded from the multiple received signal strengths, so as to obtain multiple filtered received signal strengths. A user position of the user device is obtained according to the filtered received signal strengths.
