Synchronization and Time Resolution Improvement for 802.11 WLAN OWPT Measurement

In this paper, the authors propose novel algorithms for synchronizations and time resolution improvements of One Way Propagation Time (OWPT) measurement in the 802.11 Wireless Local Area Network (WLAN). In OWPT measurement, the Mobile Station (MS) records each 802.11 beacon frame's arrival time. The beacon frame's arrival time minus its timestamp, which is recorded when the beacon frame is transmitted from an Access Point (AP), is the beacon frame's propagation time. The propagation time represents the distance between the MS and the AP.
