• 論文抄録 / 内容記述: One-sided Wi-Fi fine-time measurement (FTM) of signal round trip time (RTT) is one of the more promising solutions to adapting the Wi-Fi FTM RTT protocol on uncooperative Wi-Fi access points (AP). One of the major obstacles to this approach is the measurements have a large bias, making the raw distance measurement 5-10 times bigger than the real distance, which is unusable for positioning. There has been previous study to mitigate this, by using Gauss-Newton algorithm to perform simultaneous localization and calibration. However, the study assumed a universal offset to be applied to all APs and did not consider the case of having Wi-Fi FTM capable APs or APs that have different characteristics in the environment. This paper presents a solution to integrate such APs to improve the offset calculation for uncooperative APs.
