Multiple antennas are used to take measurements of the packet are converted into in-phase and quadrature components, then a low-pass filter is applied. The known data presents an in-phase and quadrature spectrum that is a continuous wave-tone representation of the packet signal in the passband of the low-pass filter. Multiple measurements are used to determine the phase difference of the filtered measurements at the different antenna locations. Phase difference is used to determine the location of the device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Angle of arrival and departure using standard bluetooth low energy packets","description":"Methods and systems for determining the location of a Bluetooth device using a standard broadcast packet containing known data.
