Abstract: A station device, a Wi-Fi system, and an associated positioning method are provided. The Wi-Fi system includes an AP1 device, an AP2 device, and the station device. The AP1 and the AP2 devices respectively transmit a first Wi-Fi signal and a second Wi-Fi signal. The station device receives a first-first Wi-Fi signal and a first-second Wi-Fi signal originating from the AP1 device. The station device receives a second-first Wi-Fi signal and a second-second Wi-Fi signal originating from the AP2 device. A first angle of arrival is estimated based on the first-first Wi-Fi signal and first-second Wi-Fi signal, and a second angle of arrival is estimated based on the second-first Wi-Fi signal and the second-second Wi-Fi signal. Based on the first angle of arrival, the second angle of arrival, and coordinate positions of the AP1 and AP2 devices, the station device performs a triangulation calculation to estimate its coordinate position.
