Claim 29:
30. A non-transitory, processor-readable storage medium comprising processor-readable instructions to cause a processor, of an apparatus, to:
obtain a first phase difference indication corresponding to a first difference in phase between a first signal wirelessly received, at a first time, by a wireless signaling device from a transmitter and a second signal wirelessly received, at a second time that is different from the first time, by the wireless signaling device from the transmitter; and
determine a first angular relationship between the transmitter and the wireless signaling device based on the first phase difference indication, a first virtual focal point location of the first signal, and a second virtual focal point location of the second signal, the second virtual focal point location and the first virtual focal point location being different, wherein a virtual focal point location is a location from which a signal appears to originate based on a phase surface of the signal, and wherein the first angular relationship is a first angle from a first line, connecting the first virtual focal point location and the second virtual focal point location, to the wireless signaling device.
