As a user traverses the indoor area with the mobile device, individual label identifiers are entered into the mobile device and the strength of the wireless network signals is recorded at each label position. The sampled wireless network signal strength and the corresponding label identifiers and positions are recorded to generate a mapping that identifies wireless network signal strength at each of the different label positions in the indoor area. The mapping may then be accessed to identify the locations of other mobile device users that subsequently enter the indoor area based on the wireless network signal strength from the different access points detected by the other mobile devices."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Indoor localization of mobile device using labels","description":"To localize a mobile device in an indoor area, labels are positioned at locations throughout the indoor area and signal strength is recorded at the label positions from different wireless network acce","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8538442","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.
