Further, a second signal field that includes formatting information for the data unit is generated, and a CRC field for the second signal field is generated according to the generator polynomial. Further, the data unit is generated to include i) the CRC for the second signal field and ii) a preamble having a) the first signal field, b) the CRC for the first signal field, and c) the second signal field."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Error detection in a signal field of a WLAN frame header","description":"In a method for generating data units for transmission via a wireless network, a first signal field that includes formatting information for a data unit is generated, and a CRC field for the first sig","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9819771","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.
