MIMO is very useful. It literally multiplies link rate. https://www.wiisfi.com/#MIMO https://www.wiisfi.com/#MIMO Beamforming has marginal benefit and is real. Up close your device already has max speed. Far away beamforming won’t help much. It’s in the between that helps, and mostly in the downlink direction as beamforming requires the transmitter have more antennas and DSP resources (aka the access point that’s not running on battery and does not have to be miniaturized like a smartphone). But the uplink direction is usually the range limiting factor. There’s Maximal Ratio Combining for the uplink direction but it again is not universally supported in APs.
