The method also includes, when it is determined that a preamble conforms to the first format, processing the second preamble portion according to the first format, and, when it is determined that a preamble does not conform to the first format, (i) determining whether information bits in the first preamble portion indicate a single- or multi-user data unit, (ii) when it is determined that the information bits indicate a single-user data unit, processing the second preamble portion according to a second format, and (iii) when it is determined that the information bits indicate a multi-user data unit, processing the second preamble portion according to a third format."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data unit format for single user beamforming in long-range wireless local area networks (WLANs)","description":"A method includes receiving data units each having a preamble with first and second preamble portions, detecting symbol constellation rotations of OFDM symbols in the first preamble portions, and dete","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9667462","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.
