Each OFDM symbol of the one or more OFDM symbols (i) occupies a first bandwidth, (ii) is generated with a first tone spacing, and (iii) includes a set of pilot tones. The first tone spacing is a fraction 1/N of a second tone spacing, the second tone spacing defined for the first bandwidth by a second communication protocol. The set of pilot tones includes a same number of pilot tones as defined for the first bandwidth by the second communication protocol. The data unit is generated to include the one or more OFDM symbols in a data portion of the data unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High efficiency orthogonal frequency division multiplexing (OFDM) physical layer (PHY)","description":"In a method for generating a data unit for transmission via a communication channel, the data unit conforming to a first communication protocol, one or more orthogonal frequency division multiplexing ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9832059","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.
