Physical limit for 2.4GHz is 1.11 gigabits per second or only 143 megabytes per second AT ALL. For 5GHz it’s slightly more than twice as much, but still less than even shitty cat5e, that allows 2.5GBE at 100 meters or in certain conditions 5GBE.
While with cat6 you’ll probably do 2.5gbps to 100m no problem,
Cat6 is 5gbps no problem at 100 meters and 10gbps at 55 meters.
