The new Wi-Fi standard, which has the official and technical name of 802.11be, encompasses all previous Wi-Fi revisions with lots of new features — some still are being worked out. However, you can remember four essential items below.

Organically, this new channel width is only available on the 6GHz band, with up to three 320MHz channels. However, Wi-Fi 7 can combine portions of the 6GHz and 5GHz bands to create this new bandwidth — more in the Multi-Link Operation section below.

I detailed Wi-Fi channels in this post, but generally, the new channel width means Wi-Fi 7 can double the base speed, from 1.2Gbps per stream (160MHz) to 2.4Gbps per stream (320MHz).

So, in theory, a 4×4 broadcaster 6GHz
