How is Wi-Fi speed calculated?

Question

WiFi

The question is about Wi-Fi speed.
For example, let's take the AC1200 Wi-Fi router, which has 2.4 - 300Mbps each, 5 - 867Mbps each.
There is a certain receiving device - it doesn’t matter, let’s imagine that it is ideal and supports any speed over Wi-Fi. It connects to this router at a frequency of 5G.
The question is how the speed will be distributed on this connection (ideally)? Will there be 867 Mbps for input and output, or will these 867 Mbps be the total speed from the incoming and outgoing speeds?

Answer 1

WiFi is a half-duplex concept.
That is, this is the maximum speed in one direction.
Minus the service traffic, minus the distribution for clients, minus the crooked firmware, minus the losses on the walls, minus the losses due to diffraction, minus, minus, minus.
In short, 867 megabits per second is the maximum that the standard allows, the actual porn download speed will always be lower.
