The data transfer rate is identified from a group including a legacy data transfer rate and a plurality of non-legacy data transfer rates. In response to identification of a selected non-legacy data transfer rate, a selected non-legacy modulation scheme is identified, which is associated with the selected non-legacy data transfer rate. Modulation of a data payload is performed according to the selected non-legacy modulation scheme. A non-legacy header structure is formed that includes a non-legacy start-of-frame delimiter (SFD) and an identifier of the selected non-legacy modulation scheme. Modulation of the non-legacy header structure is performed according to the legacy modulation scheme. The modulated non-legacy header structure and the modulated data payload are assembled into a non-legacy frame having a structure that is different from a legacy frame structure specified by the legacy protocol."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-rate overlay mode in wireless communication systems","description":"A method is provided, which includes identifying a data transfer rate associated with a wireless communication device.
