The electronic device includes transceiver circuitry having a beacon generator to generate a beacon at a particular frequency and direction. An antenna array transmits the beacon, and receives at least one reflected beacon from the second electronic device. The reflected beacon is received if a position of the second electronic device lies within a range of directions of the beacon. The transceiver circuitry further includes an injection-locked oscillator having an input coupled to the antenna array to receive reflected beacons, and to lock to the reflected beacon when the reflected beacon has a frequency value within locking range of the oscillator. Processing circuitry coupled to the transceiver circuitry tracks the position of the second device based on the lock condition of the oscillator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-accuracy and low-power tracking system for mobile devices","description":"An electronic device for wirelessly tracking the position of a second electronic device is disclosed.
