During the preamble detection interval, power is applied to receiver components, and during the sleep interval, power is not applied. The duration of the preamble detection interval is equal to a preamble sensing interval, and if a preamble is detected, power remains applied to a preamble processor for a preamble processing interval. The duration of the sleep interval is the duration of a long preamble less the sum of two times the preamble detection interval plus the preamble processing interval. Phase lock loop (PLL) power is applied a PLL settling time prior to and during the preamble detection interval."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Low power wireless receiver for congested networks operating with beacon frames","description":"A wireless receiver has a preamble detection apparatus and method which waits until the expected arrival of a beacon frame, after which power is cyclically applied during a preamble detection interval","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9742412","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.
