We design and implement a low cost, easy to deploy and lightweight location tracking solution that operates without the need for a fixed infrastructure. We call it "WiFi radar," which uses the signal strength of radio transmissions to determine the position (distance and direction) of devices with near linear approximation. Notwithstanding the challenges that radio frequency signals pose for location determination, the accuracy and precision of our system is relatively high. Our application is user-friendly, customizable and shows graphical as well as list views of the located objects. To the best of our knowledge, our system is the first endeavor that implements a location tracking system without the use of any fixed infrastructure and it may be the cheapest solution built so far.
