I think the suits between Apple and Qualcomm also are at play...Well You really cant blame Apple for not supporting something when the feature is not properly implemented.
I wouldn't say the hardware updates have been "constant" for 11ac.But this got me extremely worried with 802.11ax.
Are we going to repeat this again, basically constantly shipping updated Hardware Chips to the market.
All I have shown is that MU-MIMO doesn't deliver the promised improvements,Great article Tim!
Anyways I have claimed it before and will still do so. In order to increase capacity on a single AP/Router the triband solutions are the only valid option.
Even an old device as RT-AC3200 is better suited to handle multiple devices than 4x4 MU-MIMO routers. So even though many find triband routers overkill they do actually work unlike devices relying on MU-MIMO to increase capacity. And now Tim has proved this.
I also completely agree. Smart Connect is not worth it IMO. But the fact that you still have an extra 5GHz network does increase capacity if you manually assign the proper devices to use. I basically split the two 5GHz networks between low performance devices on the first and a few high performance devices on the second. That way I can keep 1x1 devices from unnecessarily slowing down the 3x3/2x2 devices. And it works regardless of clients unlike MU-MIMO.All I have shown is that MU-MIMO doesn't deliver the promised improvements,
"Smart Connect" is another can 'o worms. Yes, the additional radio helps increase total bandwidth, IF devices are properly assigned among the three radios. But that rarely happens automatically. Clients can often resist being band steered. When I have tested Smart Connect in past reviews, I've found it to be pretty stupid...
That's an easy one merlin it uses a custom boardcom AI chip to intelligently provide bandwidth to applications that needs it the most.While playing Buzzword Bingo, here's a new one I came accross recently, as part of Broadcom's new HND platform:
Adaptive Bandwidth Control
No idea what it does...
Yes.Are we going to repeat this again, basically constantly shipping updated Hardware Chips to the market.
Informed insight - has nothing to do with the Apple/Qualcomm stuff (which really doesn't have a place here - there are better forums for that discussion)I think the suits between Apple and Qualcomm also are at play...
Yep - it's not observed in the wild often, but it's out there - mostly in enterprise/carrier grade AP's, and usually under heavy use - I've got a few PCAP's where it's been caught.11ac has as part of the standard the ability to change channel bandwidth on a frame-by-frame basis. 11ax has the same.
Shareholders benefit from increased sales of WiFi NIC's that support "Smart Connect" - to the end user, it can introduce a level of complexity that offers little benefit."Smart Connect" is another can 'o worms.

It's a hard story to tell, and a hard story to sell - there is benefit, but it's not a single client benefit - and MU does work in certain use cases, esp. under heavy usage where client stations are relatively fixed.If you call selling futures on features that never show up and when they do don't work well, then ok, it's a "marketing" problem.
I wasn't aware of that. And, of course, none of the companies announcing products have shared that information.The IEEE ax Task Group did not approve Draft 1.0 of the standard as expected this year.
Looks like they've moved on to work on Draft 2.0.
- The working group letter ballot #225 on the IEEE 802.11ax draft 1.0 was conducted from December 1st, 2016 to January 8th, 2017.
- The 802.11ax draft 1.0 did *NOT* meet the requirement of >= 75% approval ratio.
- Over 7300 comments received.
- About 4700 out of 7300 comments are technical and general comments.
It gets better. Apparently some 18 companies in a prticipating SIG ("DensiFi") got caught colluding, which set things back a bit. Fun reading if you have nothing better to do. I see that the Wikipedia entry for 802.11ax has had the incident edited out.
