I'm okay with higher throughput = more bandwidth used. That is the promise of 6GHz in any event, correct? I just hope that 8 antennae solutions (4 external, 4 internal) will be more widely available.
What is AC/AX on 5GHz better than N on 2.4GHz for an IoT device?
You guys know the main way Wi-Fi 7 increases throughput is by using more bandwidth, i.e. 320 MHz channels and 4096 QAM? Which means you get those big numbers only in 6 GHz.
In 2.4GHz/ISM, sure would be nice to fully deprecate 802.11b (along with WPA(1)) - the airtime savings alone would make ISM band a lot more efficient than it is with B/G/N in play, and goes without saying that HE mode (11ax) in 2.4 would also benefit.
I suspect it will take another upgrade of clients, too.
Not going to happen soon for cost saving reasons. If something new is 10 cents more expensive, but the old one is good enough - it's out. Amazon sells "smart" plugs for under $10, manufactured for under $2. What technology improvements to expect? Profits come first.
OpenWRT already defaults to g/n for 2.4Ghz, removing the 11b support
And so long that client manufacturers will keep providing clients that barely use the capability of the standard (i.e. using only two streams), these new standards will keep getting knee capped by underperforming clients, and will remain big marketing numbers with limited performance impacts in the real world.I suspect it will take another upgrade of clients, too. It's unlikely current RF front ends don't have the bandwidth and/or lower EVM to support all those new (and much closer together) constellation points.
Two streams will continue to be the norm for mobile devices. That's why wider channels and higher QAM do the heavy lifting. More streams are gravy.clients that barely use the capability of the standard (i.e. using only two streams),

But yes, the BNOB will always be based on best case (most streams, highest link rate, widest channel). The marketing games continue.

While I agree that 2 streams is enough for a mobile device, I think there is certainly a market for laptops to start supporting three streams (Apple used to if I recall). Even desktop wifi have been largely limited to two streams these past few years (as a lot of them are just reusing the Intel AX200/AX210).Two streams will continue to be the norm for mobile devices. That's why wider channels and higher QAM do the heavy lifting. More streams are gravy.
Then why sell routers and advertise standards that virtually zero client can take advantage of?Most clients just don't need this performance.
That's why I feel that these newer standards are largely marketing smoke.
I suppose marketing can and do claim with MU-MIMO they can serve multiple clients
As for Apple in a sense @sfx2000 yes they’re conservative in adopting new technologies till they are perfected in a sense, but at times it seems like an excuse to also cheap out with components; like the Intel vs Qualcomm cellular modem iPhone 8 / X instance, where they gimped the QCA variant to perform close to the inferior Intel one, rather than just use QCA for all phones. Granted part of that was due to a spat with Qualcomm.
Even today's AX. The number of AX router models exceeds the number of available AX clients. Average family users with average Internet activities won't notice substantial difference between 5GHz N, AC and AX. Just take a look around how many people upgraded to AX routers because of few new AX mobile devices. And the single more capable AX client is on 160MHz wide channel for unknown reasons.
This was advertised even before the chipsets were capable of doing MU-MIMO. Asus was selling RT-AC88U MU-MIMO router with not working MU-MIMO in BCM4366B1, for example. Do you remember seeing "sorry guys, here is partial refund for you" apology offer? Some early models RT-AC88U users still believe MU-MIMO enabled in Professional settings is actually doing something good.
