What the standard defines
Wi-Fi 7 is the certification name for equipment built to IEEE 802.11be, an amendment whose stated aim is extremely high throughput. Three of its additions account for most of what is claimed on packaging.
Wider channels. The amendment allows channels up to 320 MHz, twice the widest that came before. A channel that wide has to be assembled out of contiguous spectrum, and in practice that means the 6 GHz band.
Denser modulation. The amendment adds a higher-order constellation than its predecessor, which carries more bits in each symbol. Denser modulation needs a correspondingly cleaner signal, so it is used close to the access point and the link steps back down as conditions change.
Multi-link operation. This is the structural change. A client and an access point that both support it establish and hold links on more than one band at the same time, and traffic moves across them. That can be used for aggregate rate, or for keeping a session alive when one band becomes congested — the amendment defines the mechanism and leaves the policy to the implementation.
Alongside those, the way a channel is divided among devices is made finer, so a single transmission can be shared out more precisely than before.
What it does not promise
It does not promise the BE figure. Like every class number in wireless, it is the sum of the theoretical peaks of separate radios, and adding the bands together is exactly what makes it large.
It does not promise 320 MHz. That width requires spectrum a national regulator has to have opened, and where less of the 6 GHz band is available, the widest usable channel is narrower. This is the single specification most likely to differ between two countries selling the identical box.
It does not promise multi-link operation to a client that cannot do it. The mechanism is a negotiation between two ends; a phone that implements one link gets one link.
It does not promise the densest modulation at the far end of a flat. That scheme is a best-case rate for a strong, clean signal, and it is the first thing a link gives up.
And it does not touch the connection arriving at the building.
What it works alongside
An 802.11be access point serves earlier-generation clients on the bands it shares with them, at the rates those clients speak. Units built to it commonly carry Ethernet ports rated above a gigabit, because the wired side would otherwise be the ceiling on everything above — worth reading before the class figure, since a port speed is a fact and a class figure is an addition.
The questions that come up before an order
What does the BE figure on the box count?
The same thing every class figure counts — the theoretical peak rates of each radio in the unit, added together. It is a quantity defined by the standard from channel width and stream count, and no single connection reaches it.
Does the widest channel exist everywhere?
No. A 320 MHz channel needs that much contiguous spectrum in the 6 GHz band, and how much of the band is open varies by country. Where less is available, the widest channel a unit can form is narrower, whatever the specification sheet says.
