The indoor positioner has an array antenna to receive a wireless signal from user equipment, and to calculate the angle of arrival (AOA) of the wireless signal according to the phase difference and the time difference. The wireless signal includes status data of the user equipment. The positioning engine server converts the angle of arrival into a set of coordinates that correspond to a position of the user equipment, and inputs the set of coordinates to an IMM module. The IMM module includes a first state module and a second state module. The IMM module calculates weighting values for the first state module and the second state module according to the status data of the user equipment, and outputs an estimated set of coordinates according to the set of coordinates and the weighting values."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic device and method for improving smoothness and precision of positioning","description":"An electronic device includes an indoor positioner and a positioning engine server.
