This poster shows the working principles behind distance estimation with Bluetooth Low Energy . The first block shows why phase is related to distance and why a simple algorithm doesn't work. The second block shows a more complex algorithm using the Frequency response of the two way channel in order to estimate the distance of the Line of Sight signal.
