[0002] AOA (Angle of Arrival) positioning technology is a positioning method based on the angle of arrival of the signal, which is widely used in indoor positioning, Internet of Things, intelligent transportation and other fields. The configuration of AOA positioning base station is one of the important factors affecting its positioning accuracy.
