In the manner, the positioning signals reach the communication device when the communication device's antenna is on for listening to a synchronization signal of the cellular network. Processing the times of arrival of the positioning signals by a server in communication with the communication device enables accurate positioning of the communication device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Accurate indoor positioning with cellular signals","description":"A system for accurate positioning of a communication devices includes a plurality of positioning cells configured for synchronizing to the cellular network and to each other, and for emitting position","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9813877","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.
