Abstract: A method of using a first device to locate a second device is disclosed. The first device, while in a first mode, transmits a first signal and receives a second signal comprising a reflection of the first signal by the second device. The first device determines, based on the received second signal, a position of the second device relative to the first device. The first device transitions to a second mode, and while in the second mode, receives a third signal from the second device. The first device determines, based on the third signal, an orientation of the second device relative to the first device. The first device comprises one or more receiving antennas, and the second device comprises one or more transmitting antennas. The third signal corresponds to a transmitting antenna of the second device.
