All rights reserved.We present a study of the robustness in the estimation of the Direction of Arrival (DoA) of Wi-Fi mobile devices using amplitude-monopulse systems, with respect to variations in the transmitted power of Wi-Fi packets and hardware heterogeneity. This variation can be due to different transmission power levels, or due to hardware heterogeneity between different chipsets used in distinct mobiles devices and Wi-Fi readers. In any case, it is shown that the estimated DoA is stable within a mean error of 2.64º, with respect to variations in the measured RSSI. This allows using the RSSI-based monopulse technique to localize Wi-Fi terminals despite the strong heterogeneity of devices and dynamic range variation of transmitted power.
