Claim 10:
11. The angular relationship determination method of claim 10, further comprising:
obtaining, at the apparatus, a second phase difference indication corresponding to a second difference in phase between a third signal wirelessly received, at a third time, by the wireless signaling device from the transmitter and a fourth signal wirelessly received, at a fourth time that is different from the third time, by the wireless signaling device from the transmitter; and
determining, at the apparatus, a second angular relationship between the transmitter and the wireless signaling device based on the second phase difference indication, a third virtual focal point location of the third signal, and a fourth virtual focal point location of the fourth signal, the fourth virtual focal point location and the third virtual focal point location being different, wherein the second angular relationship is a second angle from a second line, connecting the third virtual focal point location and the fourth virtual focal point location, to the wireless signaling device;
wherein a first direction of a first vector from the first virtual focal point location to the second virtual focal point location is different from a second direction from the third virtual focal point location to the fourth virtual focal point location.
