A described technique includes transmitting a sounding packet to a wireless communication device(s) to determine characteristics of spatial wireless channels, the sounding packet being based on a spatial mapping matrix; receiving a feedback packet(s) from the device(s), the feedback packet(s) being indicative of one or more feedback matrices, the one or more feedback matrices being derived from wireless channel estimations that are based on received versions of the sounding packet; generating spatially steered data packets based on multiple data streams and one or more steering matrices, which are based on the spatial mapping matrix and the one or more feedback matrices; and transmitting a frame that includes the spatially steered data packets to the device(s). The spatially steered data packets can concurrently provide the streams respectively within the frame to the device(s) via different spatial wireless channels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sounding and steering protocols for wireless communications","description":"Systems, apparatuses, and techniques relating to wireless local area network devices are described.
