The frame may include a first signal field, a second signal field, and a data field. The first signal field may have a duration of 4 μs and may include a first signal portion and a first guard interval. The second signal field may have a duration of 4 μs and may include a second signal portion and a second guard interval. The data field may include at least one data symbol that has a symbol duration of 12.8 μs, excluding any guard interval duration. A station may detect the frame and process the frame. Other methods, apparatus, and computer-readable media are also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"PPDU format preamble design","description":"In an example of wireless communications, an access point may generate a frame and provide the frame for transmission to one or more stations.
