The supporting chipset may be configured to operate as a sensor to receive continuous tone (CT) signals or round-trip time (RTT) packets exchanged between the main ranging device and the target device in a timeslot of a ranging cycle to improve the accuracy of the range estimates. In a different timeslot, the supporting device may operate as a transmitter to transmit CT signals or RTT packet on a channel adjacent to the channel used by the main ranging device to protect the CT signals or the RTT packets transmitted from the main ranging device against symbol level attacks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optimized secure phase-based positioning","description":"Disclosed are techniques for time-multiplexing between sensing and adjacent signal transmission functionalities on the same hardware platform, such as a chipset supporting a main ranging device in pas","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11470450","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
