Systems and methods for selecting operating mode based on relative position of wireless devices

Abstract:

Systems and methods are provided that may be implemented to configure and/or reconfigure device operating modes based on relative position of a wireless transmitter to a wireless receiver that is receiving a wireless radio frequency (RF) signal transmitted from the wireless transmitting device, or vice-versa. The relative position of a wireless transmitter to a wireless receiver may be determined using any suitable technique, e.g., using Time Difference of Arrival (TDOA) of a signal received at separate antenna elements of an antenna array of the wireless receiver, using Angle of Arrival (AoA) of a signal received at an antenna array of the wireless receiver, using measured received signal strength (e.g., received signal strength indicator (RSSI) or received signal decibel-milliwatts (dBm)) of a signal received at different antenna elements of an antenna array of the wireless receiver, using Angle of Departure (AoD) of a signal transmitted from an antenna array of the wireless transmitter, etc.
