Which 802.11 standards support channel bonding?
n, ac, and ax
(wifi 4, 5, and 6)
What is Channel Bonding?
Where you combine 2 wifi channels (contiguous or not) into one which increases throughput
What’s the difference between “bandwidth” and “throughput”?
Bandwidth is theoretical
Throughput is realized
