Abstract
The conventional positioning systems require the users to carry an electronic device, which helps in the localization process. Device-free Passive Localization (DfPL) techniques are used to position the users in a passive manner such that they do not engage in the process. A typical DfPL setup comprises of Wi-Fi Access Points (APs) that transmit periodic signals to Monitoring Points (MPs). Any intrusion within the area of interest is detected by constantly examining the strength of Wi- Fi signals received at MPs. In this paper, we examine DfPL using 1 AP and 1 MP to estimate the speed of motion in a given indoor area. The proposed method is shown to achieve high accuracy.
