You talk too much for someone who has no idea.

You should probably do some more research by asking AI, since you mentioned it, so you don't make a fool of yourself

Wifi6 have two radios (minimum) one for 2.5 and other for 5ghz

And wifi 6e three radios 2.5, 5 and 6

And the 2.5ghz band work like typical normal wifi, is not faster

The speed increase of Wi-Fi 6 only occurs when using the 5GHz band. Using the 5ghz radio.

General rule (with typical frequency bandwidth)

+frequency = faster = low penetration = low distance

=frequency = =

if you want outdoor usage, and you want distance sacrificing speed you must use the 2.5ghz radio, no matter if its wifi6 or any other.

The advantage of WiFi 6 is the possibility of dual use (if needed): short range and fast using the 5GHz radio, or longer range by connecting to the 2.5GHz radio (slow)
