Abstract
The present disclosure includes systems, apparatuses, and techniques relating to wireless local area network devices. Systems, apparatuses, and techniques include communicating with multiple wireless communication devices to determine characteristics of spatial wireless channels, determining steering matrices based on one or more outputs of the communicating, and transmitting signals that concurrently provide data to the wireless communication devices via different spatial wireless channels. The signals can be spatially steered to the wireless communication devices based on the steering matrices.
