I haven't seen anybody doing true 3x3 outdoors at any decent range, as of yet.
3x3 and beam forming would come in handy on 2.4, both of which are available with 802.11n specs, just rare as hen’s teeth in practice.
You’d think someone could convince Atheros to build the chip.From: Jaime FinkSent: Friday, March 13, 2015 4:32 PMTo: [email protected] ; Bill PrinceSubject: Re: [AFMUG] AC spec available in 2.4?Chips that are 2 stage without integrated RFIC I think you will see will work just fine with no cost hit at all.You’re right though, most high volume chips are highly integrated chips with PA and RFIC, and clearly not focused on moving into this space (read: chips for mobile phones and low cost home router Wi-Fi chips).One of the reasons we love Quantenna…clean division of baseband chip and external customizable RFIC/PA, etc.Cheers,Jaime Fink • Mimosa • CPO & Co-Founder

There are two types of beamforming, antenna based and chip/tx based.
802.11AC is significantly more efficient than 802.11N when it comes to protocol overhead, however the majority of the speed gain is from higher order modulations coupled with larger channel sizes. BTW, 160MHz wide channels are on the horizon for 802.11AC rev3.
MU-MIMO is nice.
I would not expect to ever see a 2.4GHz "AC" chipset on the mass market at "reasonable pricing", even for ISPs. Too little to gain, on various fronts.

If the only way to gain more throughput in AC (over N) is to increase the channel size, then there is no significant gain in AC.bp <part15sbs{at}gmail{dot}com>On 3/13/2015 1:42 PM, Vince West wrote:To an extent. More range, more speed, beamforming.But are you really gaining anything in the smaller channel sizes with AC in 2.4Ghz? I don't know the standard really well aside from it's obvious gains. The main things, AFAIK, that are beneficial from AC are the increased speeds and beamforming. I understand where beamforming is important. And better range.It would be interesting to know what can be gained from 802.11ac in 2.4Ghz but the main argument I have heard against it is that there isn't enough spectrum.Vince WestTower Hand

I get their explanation…. BUT… isn’t there some general efficiencies that .ac has over .n even on the same channel size?

I can't attest to the accuracy, but I found this on the web a few years ago and saved it just for a question like this.

Subject: [AFMUG] AC spec available in 2.4?
Is the 802.11ac spec only a 5 GHz spec or will we eventually see it in 2.4 Ghz?
