METHODS, DEVICES, AND COMPUTER PROGRAM PRODUCTS FOR DETERMINING RELATIVE DIRECTION OF REMOTE RF SIGNAL SOURCE

摘要

In a method of operating a wireless electronic device, a first angle-of-arrival is determined for a short-range wireless signal that is received at multiple antennas of the wireless electronic device from a signal source. Movement of the wireless electronic device is detected, and a second angle-of-arrival of a short-range wireless signal from the signal source is determined responsive to detecting the movement of the wireless electronic device. A relative direction of the signal source with respect to the wireless electronic device is identified based on an angular shift between the first angle-of-arrival and the second angle-of-arrival, relative to the movement of the wireless electronic device. Related wireless electronic devices and computer program products are also discussed.
