“CSIR (CSI at Receiver) plays a pivotal role in beamforming applications where antenna arrays steer beams towards desired directions using estimated CSI.”

Thanks for the link - took a look. Nice quick and dirty intro. I’m familiar with basic beamforming; phased-array radars.

Just bought a replacement router that claims beamforming capability. The fallout looks interesting, but not cheerful about the motion detection and classifying.

Again, thanks for the link

Take Care.

Several makers of hearing aids also leverage this tech.
