Abstract: Methods and apparatuses of improving quality of positioning are disclosed. According to aspects of the present disclosure, a transition from a short training field to a long training field in one or more communication messages between two wireless stations may be detected. A station may then determine a first arrival correction time based on the transition from the short training field and the long training field. With the first arrival correction time, more accurate timing of communications between the two wireless stations may be determined and used for improving quality of positioning applications.
