Just quickly the new WiFi standard, 802.11ax WiFi6) brings big differences to 80211ac including MU-MIMO or Multi User MIMO (Multiple Input Multiple Output). 802.11ac allows for this in the download direction, to the end points, and only in 5GHz, where as 802.11ax allows the AP to also receive from multiple stations on different spatial streams in both 2.4 and 5GHz.

Now WiFi6E also includes the 6GHz band, which currently has been used in Australia for long distance microwave transmissions. The new WiFi band has a lot of channel space available. Infact per the image below it looks like we will never again have to struggle to get a channel that isn’t congested. Now that image is for USA and doesn’t necessarily apply to Australia just yet.

Vendors are rushing to bring WiFi6 and WiFi6E AP’s and routers to market but there don’t seem to be many compatible end user devices capable of justifying the investment just yet. If you are forced to upgrade right now, consider it, but if you already have investment in 802.11ac, you don’t have to worry. When these chipsets are shipping in devices as standard, thats when an upgrade to 6E might be worth it, but for now, a well installed 802.11ac nework will be the best way to go for now as all devices will be able to operate on a new WiFi6 networks when you do upgrade.
