Is this still true with OFDM and subchannels or whatever it's called?
Also MIMO.
And don't think it's relevant to compare what to do in a large space with what one should do at home. The requirements are entirely different.
In a large space with many users I'd use small channels and many access points. I want it to work good enough for everyone to have calls, and have good aggregate throughput.
In a two bed home I'd use large channels and probably only one AP. Peak single device speed is MUCH more important than aggregate speed.
And in a home it matters much more what channels are being busyed by neighbors.
For latency, of course, there is only wired. Even with few devices.
