Bluetooth Direction Finding
The Bluetooth 5.1 specification enhances location services with a direction finding feature that makes it possible to detect the direction of a Bluetooth signal. With Bluetooth direction finding, developers can bring products to market that understand device direction and achieve sub-meter location accuracy.
Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) are the technologies that establish a standardized framework for indoor locationing. With these technologies, the fundamental problem of locationing comes down to solving the arrival and departure angles of radio frequency signals.
