Abstract

To achieve accurate wireless-local-area-network (WLAN) positioning, the directivity and influence of multipath fading on the power absorption by the user are clarified experimentally. Based on the results, a general model of the power absorption by the user is devised. The parameters of the model are estimated using maximum-likelihood estimation (MLE) and the magnetic sensor built into modern smartphones. The proposed method compensates the power absorption and the influence of multipath fading. According to experimental evaluations, the root-mean-square error (RMSE) of the proposed method is 34% lower than that of the conventional one. Namely, RMSE of the proposed method is 1.94m in a room.
