Abstract: A method for phase ranging of a personal area network device includes receiving an initial personal area network packet and storing header information contained in the initial personal area network packet. A phase shift is measured utilizing information transmitted in place of the stored header information in at least one incoming personal area network packet. A range of the personal area network device is calculated based on the phase shift of the information transmitted in place of the stored header information in an incoming personal area network packet.
