Dual-stream SIG field encoding allows for the utilization of higher order modulation schemes, such as quadrature phase-shift keying (QPSK), which increases SIG field capacity. Dual-stream encoded SIG fields are transmitted using an omnidirectional beam to allow mobile stations to accurately decode the SIG field irrespective of their spatial location."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dual-stream signal (SIG) field encoding with higher order modulation","description":"Signal (SIF) field capacity can be significantly increased by encoding SIG field data using two streams in accordance with a space-time block code (STBC) encoding scheme.
