The short-range communication methods include NFC, RFID, Bluetooth®, short-range 802.11, Wi-Fi Direct, and high frequency focused beams such as 60 GHz. The position reference devices are passive or active NFC tags, passive or active RFID tags, other devices that include such tags as their components, Bluetooth®-enabled devices, 60 GHz-enabled devices, and 802.11 access points that can lower their transmit power. The reference devices are located at various indoor and outdoor locations such as smart posters, kiosks, ATM machines, malls, store checkout counters, store security gates, wireless access points, cellular base-stations, tollbooths, traffic lights, and street lamp posts."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed method and system for determining the position of a mobile device using long-range signals and calibrating the position using short-range signals","description":"A method and system is described where a plurality of position reference devices use short-range wireless communication protocols to transmit positioning assistance data to nearby mobile devices, and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832602","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.
