Wi-Fi 6 Release 2 revealed

No, that's something entirely different, that just mean that the integrated 2.4GHz and 5GHz radios can be used at the same time, several companies can do this, so it's nothing unique to QCA. Hence the link to QCA's website, where they states it's called FastConnect.

FastConnect is just a model/platform naming scheme not a feature in itself.

I think you're not understanding the difference here. FastConnect is what allows you to connect to a 2.4 and 5GHz to the same router/AP and combine the two into a single "link", simultaneous dual band doesn't allow you to combine both into a single link, although both can be used independently of each other, something many older WiFi chips can't do.

Mobile Wi-Fi 6 performance with 4-stream DBS [video]

Immersive mobile experiences are built on the foundation of tech innovation. One such breakthrough — unique to Qualcomm FastConnect mobile connectivity systems — is 4-stream DBS...

Right, fair enough, but it's till not DBS, it's Wi-Fi Dual Station they call the option that allows you to link the 2.4 and 5GHz radios for a single "fat pipe. Obviously it wouldn't work without DBS, but it's not a feature unique to QCA.

No Dual station is not a fat pipe. Yeah marketing is a bit vague unfortunately, confusing people.

“Wi-Fi Dual Station does not aggregate the total speed of these streams since they are effectively streaming the same data in parallel. So, while this technology will improve latency and jitter, it is unlikely to improve speeds.”

That article is still the only place I've seen reference to "Double Connect". I'm skeptical of claims from Killer, given its past exaggerations about its latency reduction capabilities.

And this is why I used wired networking for gaming...

This is just all pointless then.

Yeah what Killer brand’s as DoubleShot, that’s closest to what you were looking for, originally it was combining one WiFi band and Ethernet like link aggregation and now it can do it across two WiFi bands meaning still not exactly one big pipe but rather prioritizing data across one band or the other using their QoS system. Never been a fan of Killer’s QoS software in general, always caused more problems than being a boon.

 

[thiggins]

This is a very confusing situation. I'm setting aside Intel for the moment because I can find no technical details from Intel about "Double Connect".

Qualcomm 4 Stream Dual-Band Simultaneous technology has a video explainer here. https://www.qualcomm.com/videos/4-stream-dual-band-simultaneous

It's still vague about how the two pipes are used, but it would seem crazy to send ALL the same information over both connections. And even if that were done, the effect is still increased bandwidth because more data is sent per unit time.

The "one big pipe" analogy is as misleading here as it is with aggregated Ethernet. Higher bandwidth comes from multiple paths so that packets from multiple clients can move over different pipes. It's like running two roads next to each other going between the same two points vs. one twice-as-wide road.

Dual-Band Simultaneous is more about minimizing queing delay than increasing single stream throughput.

Wi-Fi Dual Station is based on Qualcomm DBS according to this article. https://futurumresearch.com/researc...rnet-like-latency-via-wifi-to-windows-11-pcs/

I suspect Intel "Double Connect" is similar, but can't say for sure until I see information from Intel.

 

[avtella]

A bit different from dual station, Double connect was carried over from before acquisition of Killer by Intel. Essentially link agg with their Killer QoS software suite handling the load balancing between WiFi and Ethernet, pretty much what you alluded to above . With simultaneous dual band on new cards now pretty sure same but between two WiFi bands.

The market for high-end gaming connectivity is quickly becoming one of the Wi-Fi industry's most lucrative and most hotly contested.

Quote from above article:
“Intel Double Connect Technology for example allows gaming traffic to run over 6 GHz or 5 GHz while relegating all other applications to 2.4 GHz. And of course several more 160 MHz channels are available on the 6 GHz band,” says Bob Grim.

SDB, it depends on which industry segment one is looking at... for example, in the connected car, it's this deployment scenario - where the car's WiFi hot spot is both a client and an AP, one both bands...

WiFi6 would play nicely into this - and vendors are already going there...

A good example here is the u-Blox Jody W3, which uses a Marvell/NXP chipset in the module.
