If 2.4 GHz was the paved suburban road leading to your house while 5 GHz was the major double-lane thoroughfare that takes you downtown, Wi-Fi 6E will introduce a new 6 GHz band that’s the equivalent of a massive multi-lane highway allowing many devices to operate at maximum speed at the same time. The top speeds it will theoretically allow will be on par with what the 5 GHz band offers, but the real benefit of the 6 GHz band is that will offer 59 non-overlapping channels (compared to 25 non-overlapping channels on the 5 GHz band, and just three channels on the 2.4 GHz band) which will dramatically reduce interference that’s a major contributor to reduced bandwidth speeds on a crowded network.
