What is the difference between wifi versions 1x2 and 2x2?

Question

WiFi

I saw in the specifications these versions of Wifi


Tell me, what's the difference?

Answer 1

These are not WIFI versions, but the number of MIMO channels (transmission x reception) You can read how it works here, for example: https://en.wikipedia.org/wiki/MIMO .
If we simplify it very much, in one direction the maximum achievable speed will be the same, in the other, 2x2 will have up to two times more.
