Wi-Fi 6 brings with it many improvements that accommodate the growing number of connected devices that are beginning to populate our homes: security improvements, features that allow simultaneous communication with many devices at once, and bringing stability to networks that really weren’t intended for this sort of load.
What distinguishes Wi-Fi 6E is not necessarily a new standard, but a new band. Previous iterations of Wi-Fi operate on the 2.4 and 5 GHz bands, which have grown more and more congested over time. Wi-Fi 6E will take advantage of the newly-opened 6 GHz band, which is strictly limited to only 802.11ax-and-up devices. On top of that, this band brings with it an additional seven 160 MHz-wide channels (currently, there are about 4 with normal Wi-Fi) bringing a great deal of additional headroom to a network.
