In response, a distance metric is generated to indicate a degree of similarity between the first RF background and the second RF background, and based on whether this metric satisfies a threshold, access to the vehicle may be granted via the wireless-communications vehicle-access circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Vehicle access based on RF digests/backgrounds","description":"According to certain examples, a circuit-based wireless communications system provides secure access to a vehicle by way of certain circuitry configure to compare a first RF background observed for a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11518343","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.
