Abstract: An electronic device includes an indoor positioning tag and an indoor positioner. The indoor positioning tag includes a gravity sensor. The indoor positioning tag determines whether to start to transmit a wireless signal according to the acceleration magnitude, the acceleration direction, and the duration of acceleration change detected by the gravity sensor, and adjusts the frequency of the transmission interval of the wireless signal.

Abstract: An electronic device for indoor positioning includes an array antenna and a processor. The array antenna includes a plurality of antenna units. The array antenna receives a wireless signal transmitted from user equipment. Each of the antenna units receives the reception parameters of the wireless signal. The processor executes the following tasks: dividing the antenna units into a plurality of groups; combining the reception parameters of the antenna units included in each of the groups to generate a reception parameter matrix; and calculating a plurality of angles of arrival (AOA) from the UE to the plurality of the groups according to the reception parameter matrix.
