| description | Electronic devices and methods to provide wireless ranging are shown. A first electronic device includes a memory containing stored instructions that can perform a method for determining a distance between the first electronic device and a second electronic device. For each frequency in a selected set of frequencies, the method sets the transceiver to the respective frequency, sends a first tone having the frequency and a first phase to the second electronic device and receives a second tone having the first frequency and a second phase. For each selected frequency, the first electronic device determines the phase difference between the second tone and the controllable oscillator, receives a phase difference from the second electronic device, and calculates a phase delay for the frequency. The first electronic device calculates a phase delay difference for pairs of the frequencies; and determines the distance using these phase delay differences. |
